Newton's 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 unless acted upon by an unbalanced force.

Front

Define Inertia.

Back

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

Front

What is the net force when two equal forces act in the same direction?

Back

The net force is the sum of the two forces.

Front

What happens to an object in motion when no net force acts on it?

Back

It continues to move at a constant velocity.

Front

What type of forces are required to change an object's motion?

Back

Unbalanced forces.

Front

If a car suddenly stops, what happens to the passengers inside?

Back

They continue to move forward due to inertia.

Front

What is an example of balanced forces?

Back

Two people pushing a car with equal force in opposite directions.

Front

What is the effect of unbalanced forces on an object?

Back

They cause the object to accelerate in the direction of the net force.

Front

What is the formula for calculating net force?

Back

Net Force = Force1 + Force2 + ... + ForceN.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.
