Question | Answer |
Whats Momentum? | Momentum is the product of an objects mass and its velocity. |
Whats the Fomula for momentum? | m=pv. |
Whats the law of conservation of momentum? | the total momentum of any group of objects remains the same unless the outside forces also act on the objects. |
Whats force? | a push or a pull. |
What are the units of force? | forces are measured in Newtons (N). |
Whats net force? | Net force is the total of all the forces acting on an object. |
What is inertia? | Inertia is the tendency of matter to resist a change in its motion. |
What is a Balanced force? | A balanced force is the net force acting on object that is zero. |
What are unbalanced forces? | Unbalanced forces is the net force acting on a obect thats not zero. |
Whats magnitude? | Magnitude is the amount of a measurement. |
What was Newtons first law of motion? | objects at rest will stay at rest and objects in motion will stay in motion at a constant velocity. |
What was Newtons second law of motion? | the net force acting on an object is equal to the product of the objects mass and acceleration. |
What was Newtons third law of motion? | for every action force there is a reaction force that is equal but acts in the opposite direction. |
What is the law of universal gravitation? | the net force acting on an object is equal to the product of the objects mass and acceleration. |
what is freefall? | Free Fall is the motion of a object when gravity is the only force acting on it. |
What is Terminal Velocity? | Terminal Velocity is greatest velocity of a falling object occurs when the force of gravity is equal to the force of friction. |
What is weight? | Weight is a measured force of gravity on a object. |
