Front

What is work in physics?

Back

Work is exerting a force that in turn moves an object.

Front

What simple machine is used to lift heavy objects with less effort?

Back

A lever.

Front

What does a pulley do?

Back

A pulley changes the direction of a force and can make lifting easier.

Front

How does a lever multiply force?

Back

A lever can multiply the input force, allowing a smaller force to lift a heavier load.

Front

What is an example of an inclined plane?

Back

A ramp is an example of an inclined plane.

Front

What is the formula for calculating mechanical advantage in levers?

Back

Mechanical Advantage = Load Force / Effort Force.

Front

What is a wheel and axle?

Back

A wheel and axle is a simple machine that consists of a larger wheel attached to a smaller axle, allowing for easier movement.

Front

What is the purpose of a wedge?

Back

A wedge is used to separate or hold objects apart.

Front

How does a screw function as a simple machine?

Back

A screw converts rotational motion into linear motion, allowing for fastening or lifting.

Front

What is the mechanical advantage of a pulley system?

Back

The mechanical advantage of a pulley system is determined by the number of rope segments supporting the load.
