Work

Front

What is the formula for calculating work?

Back

Work (W) = Force (F) × Distance (d) × cos(θ), where θ is the angle between the force and the direction of motion.

Front

Define work in physics.

Back

Work is done when a force causes an object to move in the direction of the force. It is measured in Joules.

Front

What is the unit of work?

Back

The unit of work is the Joule (J). 1 Joule is equal to 1 Newton meter.

Front

If a force of 10 N moves an object 5 m, how much work is done?

Back

Work = 10 N × 5 m = 50 J.

Front

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

Back

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

Front

How does the angle between force and displacement affect work done?

Back

If the angle is 0 degrees, maximum work is done. If the angle is 90 degrees, no work is done.

Front

Calculate the work done if a force of 200 N is applied over a distance of 300 m.

Back

Work = 200 N × 300 m = 60,000 J.

Front

What is the work done when a force of 50 N moves an object 2 m at an angle of 60 degrees?

Back

Work = 50 N × 2 m × cos(60°) = 50 N × 2 m × 0.5 = 50 J.

Front

If 150 Joules of work is needed to move a box 10 meters, what force was used?

Back

Force = Work / Distance = 150 J / 10 m = 15 N.

Front

How much work is done with a force of 200 N over 426 meters?

Back

Work = 200 N × 426 m = 85,200 J.
