Force Review Practice Flashcard

Front

What is force?

Back

A force is a push or pull acting upon an object as a result of its interaction with another object.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is net force?

Back

Net force is the vector sum of all the forces acting on an object.

Front

What does it mean when an object is in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero, resulting in no acceleration.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses, such as the Earth and an object.

Front

What is air resistance?

Back

Air resistance is a type of frictional force that opposes the motion of an object through the air.

Front

What is terminal velocity?

Back

Terminal velocity is the constant speed an object reaches when the force of air resistance equals the force of gravity.

Front

What is normal force?

Back

Normal force is the support force exerted upon an object that is in contact with a stable surface.

Front

What is static friction?

Back

Static friction is the force that keeps an object at rest and prevents it from moving.

Front

What is inertia?

Back

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