Force and Motion Review

Front

More mass = More inertia

Back

True

Front

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?

Back

Balanced forces, no movement.

Front

A push or pull that can change the position or motion of an object/material is --

Back

Force.

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

What is the relationship between force and motion?

Back

A force applied to an object can cause it to accelerate, change direction, or change speed.

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).

Front

What is an unbalanced force?

Back

Forces that are not equal in size and opposite in direction, causing a change in motion.
