Detailed Solution

The above statement is True.
“A machine is a device that makes our work easy.” When a machine is doing work, we have to apply very less force and give less energy. Machines are developed to perform activities with ease and efficiency. A machine can change the direction of the force. It can also increase the magnitude of force. It can change the direction of force by giving acceleration in another direction, as the direction of force is the same as the direction of acceleration.
