Question 15

What is a balanced force?

Answer 15

• Equal forces, opposite directions (the object is in equilibrium)
• There must be something balancing the object and keeping it at rest

Question 16

Friction changes the…

Answer 16

motion of an object

Question 17

Unbalanced forces cause

Answer 17

accelerations

Question 18

According to Newtons’s 2nd law, what is the relationship between Acceleration and net force (F) ?

Answer 18

Acceleration is directly proportional to the net force

a= F net/ m
