Physics 30 Unit 1

QuestionAnswer
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
