When objects collide, the contact forces transfer energy so as to change the object's motions.
When objects collide, the contact forces transfer energy so as to change the object's motions.
The statement presented in the question is correct. If two objects collide, energy will be transferred between both, and there will be a change in motion. If I were to run into a friend at recess, we would both slow down and possibly fall backward or sideways due to the force of the impact. Objects can change speed, direction, or come to a complete stop because of a transfer of energy during a collision.

Karyssa is bowling with her friends, and she is looking at the pins when they each throw the ball. Looking at the pictures of the pins, Karyssa has to make a prediction of which ball she thinks had a greater speed upon collision and why?

Both of these photos represent changes in energy during a collision. The ball is transferring energy to the pins when they make contact. Karyssa could predict based on the pictures and the positions of the pins, which she believed had a higher speed upon collision. When examining the photos, they both show pins falling and the ball making contact with the pins. The second photo shows the pins almost exploding at the end of the lane and flying through the air. A reasonable prediction could be made that this ball had higher speed upon collision because there was more energy transferred to the pins, and there was a more significant "reaction" when the crash took place.

Robert is trying to replicate the collision shown in the photograph below. Which ball would create the same change in energy?
Robert is trying to replicate the collision shown in the photograph below. Which ball would create the same change in energy?
If Robert is trying to recreate the same change in energy and have the same explosion of pins, none of these balls will work. Bowling balls are smooth, heavy, and built to create a change in energy when they collide with the pins. The baseball and tennis balls are small and light, so they will not transfer much energy to the pins. The basketball is larger but is also light and textured, so it will not roll as well and will not transfer the same amount of energy. It is more likely to knock pins down, but it will not create the dramatic explosion of pins crashing around the lane when struck.

Glen and his friend London are going sledding at a local park. There are two hills to choose from, "The Bunny Slopes," which are small hills and lots of flat surfaces, and "The Dragon," which is a steep hill and not for beginners. If London goes first and reaches the bottom and Glen crashes into him from behind on "The Dragon," what would happen to the motion of their sleds?

If London goes first and reaches the bottom and Glen crashes into him from behind on "The Dragon," what would happen to the motion of their sleds?
If London is waiting at the bottom of the hill and Glen crashes into him there will be a change in the energy transferred when the collision takes place. When Glen hits the back of London his sled will stop or slow down while London's sled will be pushed forward and move. There is a transfer of energy from Glen to London that takes place when any two objects collide.

What does the term "collide" mean? Example: Jackson and Robbie were afraid to collide when their sleds crossed paths.
What does the term "collide" mean? Example: Jackson and Robbie were afraid to collide when their sleds crossed paths.
When objects collide, it means that they are hit with force while moving. Robbie and Jackson's sleds crossed paths and nearly collided or crashed into each other. When objects collide, there is a change or transfer of energy, and the object's motion can change. The objects may change direction, speed, or stop when they collide with something else.

The diagrams below show a force on an object and its motion.
Which diagram correctly shows the relationship between the force and the motion?
The diagram that correctly depicts the relationship between force and motion is Diagram B. The force of an object is colliding with the white sphere and pushing it forward. The sphere will move in the direction it is being pushed. If two objects collide, energy will be transferred between both, and there will be a change in motion.

Another name for a change in position is "motion." Motion is the process or action of being moved or moving. The arrows are pushing against the triangle, and it will move in the direction of the energy being transferred.

Two students are rolling a ball back and forth across the playground grass. Suddenly, the ball changes direction. When the students explore why this happened, they see that the ball hit a rock.
Which of these caused the ball to change direction?

Marquise is at baseball practice. What force will most likely cause the baseball to change direction?
The force of the ball hitting the bat will most likely cause the baseball to change direction. When the batter hits the ball, there is a force applied, and energy is transferred. The ball will move in the direction the force is pushing it. If two objects collide, energy will be transferred between both, and there will be a change in motion.

True or False: The bowling ball in the picture will change directions because of the force applied by the pins.
The statement in the question is false. The ball is transferring energy to the pins when they make contact, not vice versa. The force is being applied to the pins and will cause them to move and change direction while the ball continues on its path.
