John pushed two identical toy cars across the same flat smooth floor. Why did both cars travel the same distance?

• because he pushed the cars at the same time

How will the force needed to move an object be affected if the mass of the object changes from 100 kilograms to 200 kilograms?

• The force needed to move the object would be tripled.

• The force needed to move the object would remain the same.

• The force needed to move the object would be reduced by half.

• The force needed to move the object would be doubled.

• The human is traveling at a faster speed because it reached 500 meters in a shorter amount of time.

• The cheetah is traveling at a faster speed because it reached 500 meters in a shorter amount of time.
