DESCRIBING MOTION AND FORCE LESSON 1 ASSIGNMENT

Front

What are forces that produce a net force of 0 N?

Back

Balanced forces are forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What is drag from the air classified as?

Back

Drag from the air is classified as a contact force, as it involves direct interaction between the object and the air.

Front

What is motion?

Back

Motion is when an object changes its position compared to another object.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another surface.

Front

What is gravity?

Back

Gravity is a non-contact force that pulls objects toward each other, such as the Earth pulling objects toward its center.

Front

What is a reference point?

Back

A reference point is a stationary object used to determine the position of another object.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).
