Which of these best states Newton's Second Law?

• The greater the mass of an object the greater the force needed to change its motion.

• The greater the mass of an object the less force needed to change its motion.

• The mass of an object does not effect the force needed to change its motion

20 Newtons is an example of a/an:

• mass

• weight

• force

• acceleration

Why would one object have a greater acceleration than another when pushed with the same amount of force?

• The objects have different weights.

• The objects have different forces.

• The objects have different masses.

• The objects are different sizes.
