Answer 12

A push or pull.

Question 13

What are the two types of forces?

Answer 13

Unbalanced and Balanced.

Question 14

What are unbalanced forces?

Answer 14

A force acting on an object that changes the object’s motion.

Question 15

Unbalanced forces fact:

Answer 15

Unbalanced forces cause objects to start moving, stop moving, or change direction.

Question 16

What are balanced forces?

Answer 16

Forces acting on an object that will not change the object’s direction or motion.

Question 17

Balanced forces fact:

Answer 17

Balanced forces are forces that are actively happening at the moment.

Question 18

What is net force?

Answer 18

The overall (resulting) force on an object after all forces add together.

Question 19

Forces fact:

Answer 19

Forces may also be categorized: electrical, applied, gravitational, magnetic, spring, tension, frictional, air resistance, and normal.

Question 20

What is Speed?
