Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first. Or to put another way, “To every every action there is always an opposed equal reaction”

What is, Newton's 3rd Law of Motion

What is Newton's third law of motion?

100

For forces that are part of an interaction do the directions compare in direction? And are the at the same time or different times? 

What is the forces opposite in direction and occur at the same time. 

100

If the action is A on B, then the __________

100

If foot A kicks the football (object B) then object B will....

What is Accelerate 

200

Any object or collection of objects being studied.

What is a System

200

When an object applies a force on another object, the second object applies a force of the same strength on the first object, but the force is.....


Hint: what direction? 

What is in the opposite direction?

200

In an interaction the action and reaction force are the same size. 

Example: We have a canon and a canon ball, which will experience more acceleration, why? 

What  is the canon ball, because it has a smaller mass then the canon.

300

Why don't action and reaction forces cancel out to zero? 

What is, they act on different bodies.

In the orange and apple cart shown, do the forces cancel out, accelerate the system, or stay at rest? 

What is cancel out. 

400
