An object will remain at rest or continue to move with constant velocity unless acted upon by a resultant force.
1 of 9
What is Newton's third law?
When two objects interact, they exert equal and opposite forces on eachother.
2 of 9
What are the four fundamental forces that explain all interactions?
Gravitational, electromagnetic, strong nuclear and weak nuclear.
3 of 9
What is the equation for momentum?
massxvelocity
4 of 9
What is the principle of conservation of momentum?
For a system of interacting objects, the total momentum in a specified direction remains constant, as long as no external forces act.
5 of 9
What is the difference between inelastic and elastic collisions?
In an inelastic collision, the total kinetic energy is not conserved, whereas in an elastic collision it is.
6 of 9
What is Newton's second law?
The net force acting on an object is directly proportional to the rate of change of its momentum, and is in the same direction. F= rate of change of momentum
7 of 9
What is the impulse of a force?
The product of force and the time for which this force acts on an object. Impulse = force x time so impulse = change in momentum
8 of 9
What does the area under a force-time graph show?
The impulse of the force or the change in momentum of the object.
