Forces and Motion

Front

What is the definition of position in physics?

Back

Position refers to the location of an object in relation to a reference point.

Front

What is a force?

Back

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

Front

What is the difference between a push and a pull?

Back

A push moves an object away from you, while a pull moves an object closer to you.

Front

What are the two types of forces?

Back

The two types of forces are contact forces (like friction) and non-contact forces (like gravity).

Front

How do forces affect the motion of an object?

Back

Forces can change the speed or direction of an object's motion.

Front

What is an example of a contact force?

Back

Friction is an example of a contact force that opposes the motion of an object.

Front

What is an example of a non-contact force?

Back

Gravity is an example of a non-contact force that attracts objects toward each other.

Front

What is the role of gravity in motion?

Back

Gravity pulls objects toward the center of the Earth, affecting their motion.

Front

What is the relationship between mass and force?

Back

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

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.
