Force Diagrams

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It acts in the opposite direction to the movement.

Front

What is net force?

Back

Net force is the vector sum of all the forces acting on an object. It determines the object's acceleration and direction of motion.

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal and opposite, causing a change in the motion of an object.

Front

What is the normal force?

Back

The normal force is the support force exerted upon an object that is in contact with a surface. It acts perpendicular to the surface.

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

How do you calculate net force?

Back

To calculate net force, sum all the forces acting on an object, taking into account their directions.

Front

What happens when net force is zero?

Back

When net force is zero, the object is either at rest or moving at a constant speed in a straight line.

Front

What is an example of friction in everyday life?

Back

An example of friction is when you slide a book across a table; the resistance you feel is due to friction.

Front

What is the effect of unbalanced forces on a moving car?

Back

Unbalanced forces can cause a car to accelerate, decelerate, or change direction.
