What is Mechanical Advantage (MA)?

Back

Mechanical Advantage (MA) is the ratio of the output force produced by a machine to the input force applied to it. It can be calculated using the formula MA = Input Distance / Output Distance.

How do you calculate Work (W)?

Back

Work (W) is calculated using the formula W = Fd, where F is the force applied and d is the distance moved in the direction of the force.

What is the formula for Mechanical Advantage using a lever?

Back

The formula for Mechanical Advantage (MA) using a lever is MA = Input Distance / Output Distance.

Front

If a lever has a mechanical advantage of 3, what does this mean?

Back

A mechanical advantage of 3 means that the lever allows you to lift three times the weight you apply to it.

Front

What is the relationship between force and distance in the context of levers?

Back

In levers, if you apply a smaller force over a longer distance, you can lift a larger weight over a shorter distance.

Front

What is the significance of the output distance in a lever?

Back

The output distance is the distance the load moves when the input force is applied. It is crucial for calculating mechanical advantage.

Front

What happens to the mechanical advantage if the input distance is increased?

Back

If the input distance is increased while keeping the output distance constant, the mechanical advantage increases.

Front

What is an example of a simple machine that provides mechanical advantage?

Back

A lever is a simple machine that provides mechanical advantage by allowing a smaller input force to lift a larger load.

How much work is done if a force of 350 N moves an object 5 m?

Back

The work done is 1750 J (calculated using W = Fd).

If a 16 N force moves an object and 96 J of work is done, how far was the object moved?

Back

The object was moved 6 m (calculated using W = Fd, rearranged to d = W/F).
