• speed

• weight

• direction

• gravity

According to the image, M1 velocity changed when it collided with another meteorite with the same mass. Describe how the motion of M1 changed.

• Start moving

• Stop moving

• Speed up

• Slow down

What can you infer about the strength of force exerted on M1 based on the difference in change in velocity?

• M1 had a stronger force acting on it causing it to speed up

• M1 had a weaker force acting on it causing it to speed up

• M1 had no change in velocity

• M1 had a stronger force acting on it causing it to slow down

According to the image, M1’s speed changed by 2 / 4 / 6 / 8 km/s (circle one).

• 2 km/s

• 4 km/s

• 6 km/s

• 8 km/s

Select the best claim that explains which meteorite experienced the strongest force when hit by another meteorite with the same mass.

• M1 and M12 experience a stronger force because they both gained the same force as they sped up.

• M2 experienced a stronger force because it has the fastest speed after the collision.

• M1, M2, and M3 experience the same strength force because they all changed speed by the same amount.

• M1 experienced the strongest force because it slowed down.

Select the two statements that are correct. If the same strength force is applied to two objects with different masses,

• the object with less mass will have a smaller change in velocity

• the object with less mass will have a greater change in velocity

• the object with more mass will have a smaller change in velocity

• the object with more mass will have a greater change in velocity

The red satellite had the greatest change in velocity.

• True

• False

Which satellite(s) experienced the strongest force when hit? How do you know?

• The blue and red satellites experienced the strongest force because they are both more massive than the yellow satellite and they changed speed but the same amount.

• The red satellite experienced the strongest force because it is as massive as the blue satellite and has the highest ending speed.

• All three satellites experienced the same force because they changed speed by the same amount.

• The blue satellite experienced the strongest force because it takes more force to slow an object than it takes to make it go faster.

During the collision between the asteroid and gray moon,

• the asteroid and gray moon experience different forces in the same direction

• the asteroid and gray moon experience different forces but in opposite directions

• the asteroid and gray moon experience the same force in the same direction

• the asteroid and gray moon experience the same force but in opposite directions
