If we know initial velocity (u), final velocity (v) and time (t). Then the equation for acceleration is:
The energy possessed by a body by virtue of its position is called
Kinetic energy
Potential energy
Gravitational energy
Electrical energy
Kinetic energy depends on
The square of the velocity
The velocity
The cube of the velocity
Half of the velocity

Below the equator
At the equator
Above the equator
Depends on the size of the satellite
Rate of change of velocity with time is called
Velocity
Acceleration
Average velocity
Speed
