Forces & Friction Practice 2024

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in a net force of zero.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal in size or direction, resulting in a net force that causes an object to accelerate.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting in the opposite direction of the object's movement.

Front

What is fluid friction?

Back

Fluid friction is the resistance encountered by an object moving through a fluid (liquid or gas). For example, a swimming fish experiences fluid friction.

Front

What is sliding friction?

Back

Sliding friction is the force that opposes the motion of two surfaces sliding past each other, such as a sled sliding down a hill.

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 rolling friction?

Back

Rolling friction is the force that opposes the motion of a rolling object, such as a wheel or ball.

Front

In which direction does friction act?

Back

Friction acts in the opposite direction of motion.

Front

What happens when the net force is zero?

Back

When the net force is zero, the object remains at rest or continues to move at a constant velocity.

Front

What is the relationship between mass and friction?

Back

The greater the mass of an object, the greater the frictional force acting on it.
