Which of the following represents Newton’s 1st Law (the Law of Inertia)?

• A ball rolling on a flat surface coming to a stop.

• When a car brakes suddenly, the passengers press forward against their seat belts.

• Eating food at a table.

• Running and stopping at the finish line.

What claim about acceleration is shown to be mathematically supported from the relationship between force, mass, and acceleration?

• Claim 1: a = m + f

• Claim 2: a = m / F 

• Claim 3: a = F x m  

• Claim 4: a = F / m

Acceleration is caused by a force acting on a mass.

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

When a pair of balanced forces acts on an object, the net force that results is

• greater in size than both forces combined.

• equal in size to one of the forces.

• greater in size than one of the forces. 

•  equal to zero.

When an unbalanced force acts on an object,

• the object’s motion does not change.

• the mass of the object changes.

• the object accelerates.

• the inertia of the object increases.

Newton’s first law of motion states that if a moving object is acted on by balanced forces, it will

• remain in motion at a constant velocity

• change its momentum.

• eventually come to a stop.

• accelerate.
