Can machine change the direction of force?
Machines make work easier by increasing the amount of force that is applied, increasing the distance over which the force is applied, or changing the direction in which the force is applied. That’s because a machine doesn’t change the amount of work and work equals force times distance.
Can simple machines change the direction of force?
load? Simple machines function to change the magnitude of a force or the direction of a force. They use mechanical advantage, which is also known as leverage, to multiply the amount of force exerted on a load.
Which machine is used to change the direction of force?
Pulley
Is a fan a wheel and axle?
An electric fan is considered to be a mixture of several simple machines. It includes the Wheel and Axle type, wedges, and the Inclined plane types. The blades of an electric fan are the inclined planes and the wedges. The blade is considered as a wheel, as one end of it attached to an axle on the motor.

Why is the wheel and axle important?
Wheel and axle, basic machine component for amplifying force. In its earliest form it was probably used for raising weights or water buckets from wells. Its principle of operation is demonstrated by the large and small gears attached to the same shaft, as shown at A in the illustration.
What type of energy is a pencil sharpener?
electrical energy
What type of energy is in a pencil?
If a pencil is resting on the table, it has potential energy. If it falls from the table, that potential energy has been changed into kinetic energy, the energy of motion (with a boost from the kinetic energy of whatever gave it a push). When the pencil hits the floor, some of its kinetic energy disperses.
Which type of energy conversion happens when a pen is turn on?
Chemical energy to electrical energy.
Which type of energy happens when fan is turn on?
kinetic energy
