Force & Net Force

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

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

Front

What happens to an object when a net force is applied?

Back

When a net force is applied to an object, it causes the object to start moving, stop moving, or change direction.

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 directions.

Front

If two forces of 10 N and 15 N act in the same direction, what is the net force?

Back

The net force is 25 N in the direction of the forces.

Front

If two forces of 20 N and 10 N act in opposite directions, what is the net force?

Back

The net force is 10 N in the direction of the larger force.

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.

Front

What is the relationship between mass and force?

Back

The greater the mass of an object, the greater the force needed to change its motion.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting between surfaces in contact.
