Unit 2 Review - Forces

Front

What are balanced forces?

Back

Forces that have a net force of zero, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Forces that result in a net force greater than zero, causing a change in motion.

Front

Does every object with mass have gravity?

Back

Yes, every object with mass exerts a gravitational force.

Front

What is the unit of force?

They would hit the ground at the same time.

Front

What is a free body diagram?

Back

A graphical representation showing all the forces acting on an object.

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is inertia?

Back

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

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.

Front

What is gravitational force?

Back

The attractive force between two objects with mass.
