Friction & Forces Practice

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it is in contact with another surface.

Front

What is a net force?

Back

Net force is the total force acting on an object after all the forces are combined.

Front

What does it mean if an object is moving at a constant velocity?

Back

It means that the object is moving at the same speed and in the same direction without changing.

Front

What is static friction?

Back

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

Front

What is kinetic friction?

Back

Kinetic friction is the force that opposes the motion of an object that is already moving.

Front

How do you calculate weight?

Back

Weight is calculated by multiplying mass (in kg) by the acceleration due to gravity (approximately 9.8 m/s²).

Front

What is the coefficient of friction?

Back

The coefficient of friction is a number that represents the amount of friction between two surfaces.

Front

What is normal force?

Back

Normal force is the force exerted by a surface to support the weight of an object resting on it.

Front

What happens to the net force when an object is in equilibrium?

Back

When an object is in equilibrium, the net force acting on it is zero.

Front

What is the relationship between applied force and frictional force?

Back

The applied force must overcome the frictional force to move an object.
