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 motion.

What happens when the net force is zero?

Back

When the net force is zero, an object at rest stays at rest, and an object in motion continues to move at a constant velocity.

Front

What is a force?

Back

A force is a push or pull on an object that can cause it to change its motion.

What is the unit of force?

Back

The unit of force is the Newton (N).

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.

What is an example of balanced forces?

Back

Two people pushing a car in opposite directions with equal force, resulting in no movement.

What is an example of unbalanced forces?

Back

A person pushing a shopping cart forward while another person pulls it backward, resulting in movement.

What does it mean for an object to accelerate?

Back

Acceleration means that an object's velocity is changing, which can be due to a change in speed or direction.

What is the relationship between net force and acceleration?

Back

According to Newton's second law, the net force acting on an object is equal to the mass of the object multiplied by its acceleration (F=ma).

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
