Question | Answer |
Mass*Velocity (mv) | Momentum |
Mass*Acceleration (ma) | Force |
∆Velocity/∆Time (∆v/∆t) | Acceleration |
Mass*Gravity (mg) | Weight |
Force*∆Time (F*∆t) | Impulse |
Mass*Gravity*Height (mgh) | Potential energy |
1/2mv^2 | Kinetic energy |
Mass is measured in | Kilograms (kg) |
Velocity is measured in | Metres per second (m/s) |
Momentum is measured in | Kilogram metres per second (kg*m/s) |
Acceleration is measured in | Metres per second per second (m/s^2) |
Force is measured in | Newtons (N) |
Energy is measured in | Joules (J) |
Velocity is | The rate of change of an object's position |
Force is | An influence on an object's motion |
Momentum is | The product of the mass of an object and its velocity |
Newton's first law | An object's velocity does not change without an external force |
Newton's second law | The net force of an object is equal to the rate of change of its momentum |
How is impulse found in a net force-time graph | By calculating the area under the graph |
Elastic collisions are | Collisions where the objects in a system have the same initial and final kinetic energy values |
Inelastic collisions | Collisions where the objects in a system have different initial and final kinetic energy values |
Open systems are | Systems where outside forces act on the objects within |
Closed systems are | Systems where outside forces can not act on the objects within |
Impulse is | the product of the net force acting on an object during an interaction for a period of time |
