Give an example of Newton's third law in action

rocket lifting off, jumping on the trampoline, etc..

300

This is an attractive force between any two objects that depends on the masses of the objects and the distance between them

Gravity

300
This is the momentum of a football player with a mass of 80 kg and a velocity of 5 m/s
What is 400 kg m/s
400
This is the force that opposes the sliding motion of two surfaces that are touching each other
What is friction
400

Two people are pushing a box with equal forces in opposite directions. What type of forces are acting on the car? 

a) Balanced forces 

b) Unbalanced forces 

c) Frictional forces 

d) Gravitational forces

A) balanced forces

400

This is the product of an object's mass and velocity

What is momentum

400

Unbalanced forces cause objects to

Accelerate

400
