If the net force acting on a moving object causes no change in its velocity, the object's momentum will stay the same.
<h3>What is momentum?</h3>
Momentum of a body in motion refers to the tendency of a body to maintain its inertial motion.
The momentum is the product of its mass and velocity.
This suggests that if the net force acting on a moving object causes no change in its velocity, the momentum of the object will remain the same.
Therefore, if the net force acting on a moving object causes no change in its velocity, the object's momentum will stay the same.

Answer:
Frictional force always acts parallel to two planes in contact with each other and in a direction opposite to that of relative motion of the two bodies. 2. Frictional forces are caused due to intermolecular interactions between the bodies. Frictional force is more for rough surface and less for smooth surfaces.
An electric motor converts electrical energy into mechanical energy.
What is electric motor?
An electric motor is an electrical machine that converts electrical energy into mechanical energy.
A generator is mechanically identical to an electric motor, but operates with a reversed flow of power
Hence it will convert mechanical energy into electrical energy.
Some applications of electric motor are:
Industrial fans, blowers and pumps, machine tools, household appliances, power tools, vehicles, and disk drives.
