Newton's Laws of Motion Review

Front

Who developed the three laws of motion?

Back

Sir Isaac Newton

Front

What does the first law of motion state about objects at rest?

Back

Objects at rest will stay at rest unless acted upon by an unbalanced force.

Front

What is the formula for Newton's second law of motion?

Back

Unbalanced force = mass × acceleration.

Front

What force pulls objects towards the Earth?

Back

Gravity.

Front

What is a force?

Back

A push or a pull.

Front

What is inertia?

Back

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

Front

What is the relationship between mass and acceleration in Newton's second law?

Back

The greater the mass of an object, the more force is needed to accelerate it.

Front

What happens to an object in motion according to the first law of motion?

Back

It will stay in motion unless acted upon by an unbalanced force.

Front

What is an example of an unbalanced force?

Back

A person pushing a stationary car.

Front

What is the effect of friction on motion?

Back

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