Work & Mechanical Advantage

Front

What is Work in physics?

Back

Work is defined as the product of force and the distance over which it acts. It is calculated using the formula: Work (W) = Force (F) x Distance (D).

Front

How do you calculate Mechanical Advantage (MA)?

Back

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

Front

What is the formula for calculating the Mechanical Advantage of an Inclined Plane?

Back

The Mechanical Advantage of an Inclined Plane is calculated as: MA = Length of the Plane (L) / Height (H).

Front

What is the relationship between Work, Force, and Distance?

Back

The relationship is given by the formula: Work (W) = Force (F) x Distance (D).

Front

What is the Mechanical Advantage of a Wedge?

Back

The Mechanical Advantage of a Wedge is calculated similarly to an Inclined Plane: MA = Length of the Wedge / Height of the Wedge.

Front

If a force of 4.5 N is applied to move an object and 2.7 J of work is done, how far is the object moved?

Back

Distance moved = Work / Force = 2.7 J / 4.5 N = 0.6 m.

Front

What is the Mechanical Advantage of a pulley system where the input force is 223 N and the output force is 1784 N?

Back

Mechanical Advantage = Output Force / Input Force = 1784 N / 223 N = 8.

Front

If a bulldozer does 567.6 J of work to push dirt 30.5 m, what force does it apply?

Back

Force = Work / Distance = 567.6 J / 30.5 m = 18.6 N.

Front

What is the definition of Mechanical Advantage?

Back

Mechanical Advantage is a measure of the force amplification achieved by using a tool, mechanical device, or machine system.

Front

What is an example of a simple machine that provides Mechanical Advantage?

Back

Examples include levers, pulleys, inclined planes, wedges, and screws.
