Force and Motion Exam

Front

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 the unit of force?

Back

The unit of force is called a Newton (N).

Front

What does a force do?

Back

A force is a push or pull on an object that can cause it to move, stop, or change direction.

What is the direction of a force?

Back

The direction of a force indicates where the force is applied, such as to the left, right, up, or down.

Front

What happens when two forces act in the same direction?

Back

When two forces act in the same direction, they combine to create a larger net force.

Front

What happens when two forces act in opposite directions?

Back

When two forces act in opposite directions, they subtract from each other to determine the net force.

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a force.

Front

How does mass affect force?

Back

The greater the mass of an object, the more force is required to change its motion.

What is the relationship between force and acceleration?

Back

According to Newton's second law, force equals mass times acceleration (F = ma). This means that greater force results in greater acceleration.

What is friction?

Back

Friction is a force that opposes the motion of an object. It occurs when two surfaces come into contact.
