Net Force

Front

What is Net Force?

Back

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.

Front

What does it mean when forces are balanced?

Back

When forces are balanced, the net force is zero, meaning that the object will not accelerate and will remain at rest or continue moving at a constant velocity.

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. Forces in the same direction are added, while forces in opposite directions are subtracted.

Front

What is the significance of a positive Net Force?

Back

A positive Net Force indicates that the object is accelerating in the direction of the net force.

Front

What is the significance of a negative Net Force?

Back

A negative Net Force indicates that the object is accelerating in the opposite direction of the net force.

Front

If a car has a force of 54 N forwards and the brakes have a force of 73 N backwards, what is the overall Net Force?

Back

The overall Net Force is 19 N backwards.

Front

What happens to an object when the Net Force is zero?

Back

When the Net Force is zero, the object remains in its current state of motion, either at rest or moving at a constant speed.

Front

What is an example of unbalanced forces?

Back

An example of unbalanced forces is when a person pushes a shopping cart forward with a force of 30 N while friction pushes back with a force of 10 N. The net force is 20 N forward.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.
