Changes in Motion and Shape of Colliding Objects

Which of the following is NOT a change in velocity

• Speed Up

• Stop Moving

• Continue moving in the same direction at the same speed.

• Change Directions

Match the picture with the Key Concept it represents.

• How an object changes velocity depends on the direction of the force exerted on the object.

• If the same strength force is exerted on two objects bu the objects have different masses, the object with less mass will have a greater change in velocity.

• A stronger force can cause a greater change in velocity.

The key concept shown in the picture is:

• How an object changes velocity depends on the direction of the force exerted on that object.

• If the same strength force is exerted on two objects but the objects have different masses, the object with less mass will have a greater change in velocity.

• A stronger force can cause a greater change in velocity.

Object B is more massive than Object A. If you apply the same strength force (4 clicks in the SIM) to both objects, which will have a greater change in velocity?

• Object A

• Object B

• neiither, both will have the same change in velocity.

Two asteroids crashed. The crash caused both asteroids to change velocity. Scientists want to use the change in speed and motion to figure out which asteroid has more mass. Based on the information in the diagram, which statement is correct?

• Asteroid 1 has more mass than Asteroid 2.

• Asteroid 1 and Asteroid 2 are the same mass.

• Asteroid 1 has less mass than Asteroid 2.
