Newton's Laws of Motion

Front

What is Newton's First Law of Motion?

Back

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

Front

What is inertia?

Back

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

Front

What is the force that pulls objects towards the Earth?

Back

Gravity.

Front

What is friction?

Back

A force that opposes the motion of an object.

Front

What happens to a soccer ball that is not kicked?

Back

It remains motionless until a force (kick) acts on it.

Front

What is the relationship between mass and gravity?

Back

The greater the mass of an object, the stronger the gravitational pull it experiences.

Front

What is acceleration?

Back

The rate of change of velocity of an object.

Front

What is the formula for calculating force?

Back

Force = mass x acceleration (F = m x a).

Front

What is an example of Newton's Second Law of Motion?

Back

A heavier object requires more force to move than a lighter object.

Front

What is the effect of friction on a moving object?

Back

Friction slows down the object and can eventually bring it to a stop.
