Unit 3: Force and Motion - Chapter 2 - Mass and Velocity

Mass is defined as...

• the amount of force an object has.

• the amount of matter an object has.

• the amount of velocity an object has.

• the amount of friction an object has.

Carefully study and analyze the data table.

Choose the best two conclusions that can be drawn from the data table when comparing mass and change in velocity.

• When the same force is exerted on objects of increasing mass, it's velocity will invert.

• When the same force is exerted on objects of increasing mass, it's velocity will not change.

• When the same force is exerted on objects of increasing mass, it's velocity will change less.

• When the same force is exerted on objects of decreasing mass, it's velocity will change more.

Let’s say we can’t change the force in the model. We can only change the object. However, we want our end velocity to be slow and to the left, so we should…

• replace object B with the less massive object A.

• replace object B with the more massive object C.

• keep object B the same and increase the force strength

• keep object B the same and decrease the force strength.
