2024 FLASHCARD Forces & Friction

Front

What is a balanced force?

Back

A balanced force occurs when the net force acting on an object is zero Newtons, resulting in no movement.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the net force acting on an object is not zero, causing the object to accelerate in the direction of the net force.

Front

How do you calculate net force?

Back

Net force is calculated by adding all the forces acting on an object, taking into account their direction.

Front

What is the net force if two equal forces act in opposite directions?

Back

The net force is 0 Newtons, resulting in no movement.

Front

If a net force of 400 N is acting downwards, what type of force is it?

Back

It is an unbalanced force.

Front

What does it mean if an object has a net force of 0 Newtons?

Back

It means the object is either at rest or moving at a constant velocity.

Front

What is the net force of 17 N to the right and 5 N to the left?

Back

The net force is 12 N to the right.

Front

What happens to an object when the net force is unbalanced?

Back

The object will accelerate in the direction of the net force.

Front

What is the effect of friction on motion?

Back

Friction opposes the motion of an object, acting in the opposite direction to the applied force.

Front

What are the two types of friction?

Back

The two types of friction are static friction (preventing motion) and kinetic friction (opposing motion).
