Answer 3

Inertia

Question 4

Combination of all forces that act on an object

Answer 4

Net Force

Question 5

Question 8

Force= Mass times acceleration

Answer 8

Newton’s second law

Question 9

Oppose motion between two surfaces that are touching each other

Answer 9

Friction

Question 10

Resists getting an object moving ( this is when objects are not moving
