Newtons First Law

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

Front

What is inertia?

Back

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

Front

How does mass affect gravitational force?

Back

As mass increases, the gravitational force also increases.

Front

What type of friction do objects experience when sliding down a surface?

Back

Sliding Friction.

Front

If an object has twice the mass of another, what can be said about its inertia?

Back

It also has twice the inertia.

Front

What happens to a marble's speed in the absence of friction?

Back

The marble would remain at a constant speed.

Front

What is the relationship between mass and inertia?

Back

Inertia is directly proportional to mass; more mass means more inertia.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its state of motion.

Front

What is the effect of friction on motion?

Back

Friction opposes motion and can cause an object to slow down or stop.

Front

What is the difference between static and sliding friction?

Back

Static friction prevents motion, while sliding friction acts on moving objects.
