Newtons 1st Law

Front

What is Newton's First Law?

Back

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

Front

What is inertia?

Back

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

Front

What is a net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

What is an unbalanced force?

Back

Forces that cause a change in the motion of an object.

Front

What is a balanced force?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

Give an example of inertia in everyday life.

Back

A passenger lurching forward in a car when it suddenly stops.

Front

What happens to an object in space when no forces act on it?

Back

It will continue to move in a straight line at a constant speed.

Front

What is the relationship between force and motion?

Back

Force is required to change the motion of an object.

Front

What is the formula for calculating force?

Back

Force = mass x acceleration (F = ma).

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.
