Newton’s Second Law

What happens when unbalanced forces act on an object at rest?

• the object remains at rest

• the object begins moving in an unpredictable direction

• the object begins moving in the direction of the net force

• the object begins moving opposite to the direction of net force

DOK Level 1: Recall

If you push a shopping cart with a certain force and it accelerates at 2 m/s², what would be the cart's acceleration if you push it with double the force, assuming the mass remains constant?

• 1 m/s²

• 2 m/s²

• 4 m/s²

• 8 m/s²

Newton's Second Law is also known as the Law of ​ ​ (a)  

• Acceleration

• Action/Reaction

• Inertia

• Momentum

Analyze the relationship between the angle of a ramp and the force required to push an object up the ramp.

• The steeper the ramp, the less force is required.

• The steeper the ramp, the more force is required.

• The angle of the ramp does not affect the force required.

• Only the weight of the object determines the force required.
