Forces and Net Force

Front

What is the net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined. It determines the object's acceleration and direction.

What is the unit to MEASURE force?

Back

The unit to measure force is the Newton (N).

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.

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal and opposite, resulting in a net force that causes an object to accelerate.

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.

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 an example of balanced forces?

Back

An example of balanced forces is two people pulling on opposite ends of a rope with equal strength.

Front

What is an example of unbalanced forces?

Back

An example of unbalanced forces is a person pushing a car, where the force of the push is greater than the friction opposing it.

What is the effect of a net force acting on an object?

Back

A net force acting on an object causes it to accelerate in the direction of the net force.

What is friction?

Back

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