According to Newton's 2nd law,

• for every action there is an equal and opposite reaction.

• an object in motion will continue in motion in the same direction and speed unless acted upon by an unbalanced force.

• the more mass an object has the more force is needed to accelerate it. (F=ma)

• an object at rest tends to stay at rest unless acted upon by an unbalanced force

According to Newton's 3rd law of motion,

• for every action there is an equal and opposite reaction

• an object in motion tends to stay in motion in the same direction and speed unless acted upon by an unbalanced force

• an object at rest tends to say at rest unless acted upon by an unbalanced force.

• the greater the mass of an object, the more force needed to accelerate it. (F=ma)

You are sitting on Mrs. Harding's rolling chair and push off the wall with your feet. What is the reaction force?

• the rolling friction of the wall

• the air resistance of the wall

• the wall is pushing back on your feet

• your feet pushing on the wall
