Newton's First and Second Laws of Motion

A resistance to a change in motion is 

• acceleration

• inertia

• gravity

• velocity

If equal forces are applied to an object that has a mass of 35g and an object with a mass of 40g, which object is going to accelerate the most?

• the 35g object

• the 40g object

• they will accelerate the same amount

• neither object will accelerate
