What will Ashley measure to determine which car was the fastest?
Ashley will be investigating which car gets down the ramp in the least amount of time. The keyword "time" in that statement gives a clue to which answer choice would be the correct measurement. The only answer choice that measures time is, "Ashley will measure the time it takes for each car to go down the ramp.". This choice would collect information about each car so their times can be compared. The vehicle with the least amount of time would be the car that travels down the ramp the fastest.

Which tool would be best for measuring the object's movement?
The tool that would be most appropriate for measuring would be a ruler. This investigation is measuring distance so that would narrow the choices down to a ruler or the meter stick. A meter stick measures things that are a longer-distance, and a marble is not going to move a cup that far. A ruler would be sufficient for this investigation.

Taking measurements is critical when completing an experiment or investigation. The data collected through measurements can be used to draw conclusions and make recommendations. Patterns are often found in the measurements obtained, and this helps scientists to make predictions. In the investigation that Cindy is performing, the best unit of measure would be inches. Pounds wouldn't be appropriate for measuring distance, and miles are too large of a unit for something like a rolling marble. Millimeters are a tiny unit of measure, and it would be difficult to use them to measure. Inches would be the most appropriate.

There is no way to measure an object's motion. When something is moving, it cannot be measured.
There is no way to measure an object's motion. When something is moving, it cannot be measured.
The statement in the question is false. Objects can be measured when they are in motion. The object's speed is one example of a measurement that can be taken while the object is moving. Think about a baseball game, they record the speed of the ball and display it on the screen every time a pitcher throws the ball. In car races, the speed of the cars is measured to determine how fast they are traveling.

Observations are critical in an investigation because scientists are recording what they see, and they measure to collect data for evidence. The observations help support the conclusion that is made. For Ashley's investigation, the most reasonable observation would be, "The toy cars on the grass and carpet moved very slowly, if at all. The cars on the wood and plastic moved quickly. The car on the plastic got down the ramp in the least amount of time.". This statement includes information about which cars move slowly, quickly and the fastest. The data collected sounds reasonable, cars on wood and plastic would move swiftly, and vehicles on grass and carpet would move slowly.

What observation can be made regarding the motion of this object after being rolled on a curved ramp?
This investigation consists of dropping the ball onto one side of the ramp and then measuring the height each time the ball reaches the opposite side. When looking at the visual and the data table, it can be observed that the height decreases with each roll. The tick marks show the ball ending up in the center by the fifth roll, and the data table shows a steady decline in the numbers.

Each time the ball completes a roll, it decreases in height. What increment is it reduced by with each turn?
Each time the ball completes a roll, its height is reduced by 2 inches. Simple subtraction can be used to find the difference between each turn. This information can be used to make a production about future trials or the missing fifth roll.

This data table organizes information and measurements collected during an investigation of an object's motion. The cup moved every time a marble was rolled into it. An accurate observation that could be made is that the heavier the marble was, the further the cup traveled. A pattern can be seen as the marble's weight increases; the distance the cup travels increases as well.

How do objects move?
Force can make things move, change shape, or change their speed. Some forces are direct and happen when two things touch (like pushing a friend on a swing) or other happen over a distance (such as a magnet drawing a paperclip closer). Objects only move when there is a force acting on them.

Annie observes an osprey carrying a large fish back to its nest. The osprey seems to be having difficulty flying. It is sinking and dipping towards the ground and has to flap hard to stay in the air. An osprey with no fish in its feet has no trouble flying to its nest.
Why is the motion of the osprey carrying the fish different than the one who is not?

Why is the motion of the osprey carrying the fish different than the one who is not?
The osprey carrying the fish has more mass (weighs more) than the osprey that is not taking a fish back to the nest. When something has more mass, gravity has more of an effect on it. Gravity works from a distance, so even though the osprey is not touching the ground, it is still affected by gravity. Annie can observe the motion of the birds and compare the movements.

Heidi is throwing a baseball in the backyard. No matter how hard or high she throws the ball, it comes right back down. What force is acting on the ball and brings it back down to the ground?
Heidi is throwing a baseball in the backyard. No matter how hard or high she throws the ball, it comes right back down. What force is acting on the ball and brings it back down to the ground?
The reason that Heidi cannot keep the ball in the air and it keeps falling back down to Earth is because of gravity. NASA explains what gravity is, "Why do things fall when you throw them or drop them? The answer is gravity: an invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall." It is because of this that the ball returns to Earth and does not stay in the air.

Mallory went to a baseball game with her cousins. She was amazed to see how far the players could hit the ball and that it even went into the bleacher seats sometimes! She saw a player bunt the ball rather than hit it with a full swing, and the ball did not go far. Why was there a difference in the distance the two baseballs traveled?

She saw a player bunt the ball rather than hit it with a full swing, and the ball did not go far. Why was there a difference in the distance the two baseballs traveled?
When a player takes a full swing and hits a baseball, they are applying a significant amount of force to the ball and changing the direction and speed of the ball. A bunt is not a full swing, and there is less force applied. When less energy is applied to an object, its motion will not be less than an object that is hit with a greater force.

DJ notices that when he pushes his little brother on the swing at the park, the swing moves higher. He stops pushing, and slowly his brother comes to a stop. Why did the motion of the swing change?
DJ notices that when he pushes his little brother on the swing at the park, the swing moves higher. He stops pushing, and slowly his brother comes to a stop. Why did the motion of the swing change?
The motion of the swing changed because the force being applied changed. When DJ was pushing his brother, he was applying force to the swing changing its motion, speed, and direction. When he stopped pushing, the energy was removed, and there was nothing to keep the swing moving. Eventually, the swing came to a stop, and it will not start moving again unless another force is applied to it.
