What is Mechanical Advantage?

Back

Mechanical Advantage (MA) is the ratio of the output force produced by a machine to the input force applied to it. It measures how much a machine multiplies force.

Front

What is the formula for calculating Work?

Back

Work (W) is calculated using the formula: W = Force (F) x Distance (d). It is measured in Joules (J).

If no movement occurs, how much work is done?

Back

If there is no movement, the work done is 0 Joules (J), regardless of the force applied.

Front

What is the unit of Work?

Back

The unit of Work is Joules (J).

Front

How do you calculate the Work done when lifting an object?

Back

Work done (W) when lifting an object is calculated as W = Weight (W) x Height (h).

Front

What is Input Force in the context of simple machines?

Back

Input Force is the force that you exert on a machine to make it work.

Front

What is Output Force in the context of simple machines?

Back

Output Force is the force that the machine exerts on the load or object being moved.

Front

How do you calculate Mechanical Advantage?

Back

Mechanical Advantage (MA) is calculated using the formula: MA = Output Force / Input Force.

Front

What is the significance of a Mechanical Advantage greater than 1?

Back

A Mechanical Advantage greater than 1 indicates that the machine multiplies the input force, making it easier to lift or move heavy objects.

What is the Work done when pushing a box with a force of 100 N over a distance of 5 m?

Back

The Work done is 500 J (W = F x d = 100 N x 5 m).
