Newton's Laws Flashcard (graded)

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is Newton's 2nd 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 3rd Law of Motion?

Back

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

Front

What is inertia?

Back

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

Front

What is a force?

Back

A force is a push or pull acting on an object.

Front

What does mass measure?

Back

Mass measures the amount of matter in an object.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is an example of inertia in everyday life?

Back

When a car suddenly stops, passengers lurch forward due to inertia.

Front

How does mass affect acceleration?

Back

A larger mass requires more force to achieve the same acceleration as a smaller mass.

Front

What is an example of Newton's 3rd Law?

Back

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