Newton's Second Law of Motion Honors

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. It can be expressed with the formula: F = ma (Force = mass x acceleration).

Front

What is the formula to calculate force?

Back

The formula to calculate force is F = ma, where F is force, m is mass, and a is acceleration.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is the unit for mass?

Back

The unit for mass is the kilogram (kg).

Front

What is the unit for acceleration?

Back

The unit for acceleration is meters per second squared (m/s²).

Front

If a 10 kg object has a force of 50 N applied to it, what is its acceleration?

Back

5 m/s².

Front

Which object will accelerate more when the same force is applied: a ping pong ball or a bowling ball?

Back

The ping pong ball will accelerate more because it has less mass.

Front

What happens to acceleration if mass increases while the force remains constant?

Back

If mass increases while the force remains constant, acceleration decreases.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to mass.

Front

How does mass affect acceleration?

Back

Greater mass results in less acceleration for the same amount of force applied.
