If an object does not move at all, what does that mean about the forces acting on the object?

Back

The forces are balanced.

Front

What do the arrows show when two forces act on an object and there is no movement?

Front

What is Friction?

Back

When 2 objects slide against each other.

Front

What is inertia?

Back

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

Front

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 a net external force.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma).
