this object that appears to stay in place is a reference point.
Velocity is negative in a moving object when the object is moving in the opposite direction of its positive reference point.
it means an object is moving based on the force of friction and gravity.
Kinetic energy
The friction of a non-moving object is called static friction. It is the force that prevents the object from moving when a force is applied to it.

the force or other moving object
it means an object is moving based on the force of friction and gravity.

The friction of a non-moving object is called static friction. It is the force that prevents the object from moving when a force is applied to it.
it may tell the speed of the moving object
The frequency of a sound wave created by a moving object will increase if the object is moving towards the observer and decrease if the object is moving away. This effect is known as the Doppler effect.
An object has kinetic energy when it is moving and not when it is at rest. When it is at rest it has potential energy.
moving
a "body" "moving body" an "object" is moving with constant velocity. [OR] a "body" is moving with constant velocity.
Friction always want to retard the motion of a moving object. So friction slows down and finally stops a moving object.
