Newton's Laws of Motion

Front

What is Newton's First Law of Motion?

Back

An object at rest tends to stay at rest, and an object in motion tends to stay in motion at a constant velocity unless acted upon by an unbalanced force.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma).

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What happens to the acceleration of an object if the mass is doubled while the force remains constant?

Back

The acceleration is cut in half.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does mass affect the force required to accelerate an object?

Back

Greater mass requires more force to achieve the same acceleration.

Front

What is the relationship between force, mass, and acceleration?

Back

Force equals mass times acceleration (F = ma).

Front

What is an example of an unbalanced force?

Back

A car accelerating when the driver presses the gas pedal.

Front

What is an example of Newton's Third Law in action?

Back

When you jump off a small boat, the boat moves backward as you move forward.

Front

What is the effect of friction on motion?

Back

Friction opposes motion and can slow down or stop moving objects.
