TEK 8.6 Newton's Laws of Motion Review

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 with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is Newton's 2nd Law of Motion?

Back

Force equals mass times acceleration (F = ma). This law explains how the velocity of an object changes when it is subjected to an external force.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is a force?

Back

A push or pull on an object.

Front

What does it mean for forces to be balanced?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces are not equal and can cause an object to start moving, stop moving, or change direction.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is mass?

Back

The amount of matter in an object, usually measured in kilograms.

Front

What is acceleration?

Back

The rate of change of velocity of an object, typically measured in meters per second squared (m/s²).

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = ma).
