What is the difference between linear and angular momentum?
Linear Momentum: For objects moving in a straight line. | Angular Momentum: For rotating objects.
What are the differences between elastic and inelastic collisions?
Elastic Collisions: Kinetic energy is conserved. | Inelastic Collisions: Kinetic energy is NOT conserved.
What is the effect of a force acting on an object over a period of time?
It causes a change in the object's momentum (impulse).
What happens to the total momentum in a closed system?
The total momentum remains constant (conservation of momentum).
What is the effect of expelling fuel with speed at rate on a rocket?
The rocket experiences a thrust force.
What is the effect of applying a force over a time interval?
It causes an impulse, which results in a change in momentum of the object.
What happens to the total momentum in a closed system?
The total momentum remains constant (conservation of momentum).
What happens when fuel is expelled from a rocket?
The rocket experiences a thrust force in the opposite direction.
