What is 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 is a balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in an object's motion.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the total forces acting on an object are not equal, causing the object to accelerate in the direction of the net force.

What does a motion graph with a horizontal line represent?

Back

A horizontal line on a motion graph indicates that the object is at rest.

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be caused by a change in speed or direction.

How do you calculate net force?

Back

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

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

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 object's mass.

Front

What happens to an object in motion if no net force acts on it?

Back

If no net force acts on an object in motion, it will continue to move at a constant velocity.
