WarmUp - Mechanical Advantage

Front

What is Mechanical Advantage?

Back

Mechanical Advantage is the ratio of the load force to the effort force in a machine, indicating how much a machine multiplies force.

Front

What is the formula for Work?

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.

Front

If a force of 350 N moves an object 5 m, how much work is done?

Back

1750 J

Front

What does it mean if a lever has a mechanical advantage?

Back

It means that the lever allows a smaller effort force to lift a larger load force.

Front

How do you calculate Mechanical Advantage for a lever?

Back

Mechanical Advantage = Load Force / Effort Force.

Front

If the distance from the effort to the fulcrum is greater than the distance from the load to the fulcrum, what can be said?

Back

The lever has a mechanical advantage.

Front

What happens when you have a long distance from the effort to the fulcrum and a short distance from the load to the fulcrum?

Back

It allows a small effort to move a large load.

Front

What is the unit of Work?

Back

The unit of Work is Joules (J).

Front

If 16 N of force is applied and 96 J of work is done, how far is the object moved?

Back

6 m

Front

What is the relationship between force, distance, and work?

Back

Work is directly proportional to both the force applied and the distance moved.
