Question

A lever

a.)Reduces resistance
b.)Multiplies force and changes direction
c.)Transmits power from one object to another
d.)Cannot move in the reverse direction

Answer 1

A lever is a simple machine that can multiply or augment a force. It can change the direction of a force, multiply force, or transmit power from one object to another.

Step-by-step explanation:

A lever is a simple machine that can be used to multiply or augment a force that we apply. It consists of a rigid bar that is pivoted at a fixed point called the fulcrum. Levers can change the direction of a force, multiply force, or transmit power from one object to another.

For example, a lever like a hammer or racket is swung by a handle. Force is applied near the fulcrum over a short distance, which makes the other end move rapidly over a long distance. This demonstrates how a lever can require a large effort force to cause a smaller force to act over a large distance.

Overall, levers are a fundamental concept in physics and are an important part of understanding how simple machines work.
