Which statement uses Newton's 3rd Law to describe a rocket launching into space?
rockets with more mass require more force to launch
rockets remain at rest until the force of the engine firing allows them to take off
rockets move forward because the exhaust moves out of the back of the rocket
rockets remain in motion as long as the engine is burning fuel
A balanced force is when
there is no net force
there is a lot net force
there is a small amount of net force
there is some net force
What is a Net Force?
The sum of all forces that are acting on a object
The total force multiplied together
The total amount of force that is applied to the object
