Forces Unit Review

Front

What is the formula for force?

Back

F = M * A (Force equals mass times acceleration)

Front

What is centripetal acceleration?

Back

Acceleration toward the center of a curved or circular path.

Front

What is the force that causes objects with mass to attract one another?

Back

Gravity.

Front

What did Isaac Newton state about action and reaction?

Back

For every action, there is an equal and opposite reaction.

Front

True or False: Friction occurs when two surfaces rub against one another.

Back

True.

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N).

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass.

Front

What is the formula for calculating weight?

Back

Weight (W) = Mass (m) * Gravitational acceleration (g).

Front

What is inertia?

Back

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

Front

What is the difference between static and kinetic friction?

Back

Static friction prevents motion between two surfaces, while kinetic friction acts on moving surfaces.
