|
Rate of change in displacement
|
|
Definition of Acceleration
|
Rate of change in velocity
|
|
Definition of Weight
|
Weight = mass x gravitational field strength
|
|
Definition of Resultant Force
|
The result of resolving all the forces acting on object.
|
|
Definition of Momentum
|
Momentum = mass x velocity
|
|
Definition of Impulse
|
Impulse = Force(Net) x time
|
|
Definition of Moment
|
Moment = Force x perpendicular distance, from the line of action of the force.
|
|
Definition of Torque of a couple
|
Torque of a couple = Magnitude of one of the forces x perpendicular distance, between two forces
|
|
Definition of Density
|
Density = mass/volume
|
|
Definition of Pressure
|
Pressure = Perpendicular component of force/cross sectional area
|
|
Definition of Work Done
|
The energy transferred is 1J when a force of 1N is applied to a body which moves through a distance of 1m, in the direction of the force.
Work Done = Force x distance in the direction of the force |
|
Definition of Kinetic Energy
|
KE =(1/2)mv^2
|
|
Definition of Gravitational kinetic energy
|
GPE = mgh
|
|
Definition of Power
|
Rate of Work Done (rate of energy transferred)
The power rating is 1 W if 1J of energy is transferred in 1 second of time. |
