What is a device that transmits force or energy?
A simple machine, such as a lever or pulley, can transmit force or energy from one point to another. These devices allow for the multiplication or redirection of force to accomplish work.
What and a device that changes the force or increases motion from work?
A lever is a simple machine that changes the direction or magnitude of the force applied to it. It can be used to increase the motion or force output from the input work.
Is motion a force?
Motion is not a force; it is the change in position of an object over time. Force, on the other hand, is a push or pull that can cause an object to move or change its motion. Forces can accelerate, decelerate, or change the direction of motion.
What is an device that changes electrical energy to energy of motion?
An electric motor is a device that converts electrical energy into mechanical energy or motion. It consists of a coil of wire in a magnetic field that generates a force to drive a shaft and produce motion. This conversion process is the basis for a variety of electrically powered devices such as fans, pumps, and household appliances.
Does the force of gravity do work on a satellite when it is in motion?
No, the force of gravity does not do work on a satellite when it is in motion because the direction of the force is perpendicular to the direction of motion.
