Newton's First Law

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

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

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

It continues to move at a constant velocity.

Newton (N) is the unit used to measure force.

No, it will keep moving indefinitely unless acted upon by an unbalanced force.

An unbalanced force is a force that causes an object to accelerate or change its motion.

A person pushing a stationary car to get it moving.

The greater the mass of an object, the greater its inertia.

Friction is a force that opposes motion, causing objects to slow down or stop.
