Doppler Effect
The change in direction of motion of a satellite is caused by the gravitational field of the planet of which it is a satellite.
yes
An object changes its state of motion when it accelerates or decelerates, usually caused by a force.
The "equations of motion" are statements that describe motion. They would not be of much use if the very thing they're used to describe caused them to change. I'll say they don't.
motion that is always constant [Either acceleration or deceleration that is called uniform motion......... motion that undergoes a change in velocity,either by changing speed or changing direction,,,,,that.s changes are called non uniform motion......
Force.
Energy applied to it.

A change in the state of motion of an object indicates that a force has been applied to it. It accelerates in response, and this appears as a change in its state of motion. It may speed up, slow down, or change direction in response to the applied force.
Acceleration can be either a change in speed or a change inthe direction of the motion even if speed doesn't change.a=dv/dt
Energy.
They can be caused by either motion of the tectonic plates. See the related question below about what causes earthquakes more more detail.
A change in speed or direction is caused by a force and is called acceleration.
