Understanding Work, Force, and Distance

The video tutorial explains how to calculate work using the formula work = force x distance. It introduces a triangle method to find work, force, or distance. Several examples are provided: calculating work done by a runner, work done moving a sled, finding the force needed to move a chair, and calculating the distance a bike is moved. The video emphasizes the use of units like newtons, meters, and joules, and concludes with a reminder to be kind.

What is the formula for calculating work?

• Force divided by distance

• Force times distance

• Distance divided by force

• Distance minus force

In the first example, what is the work done by the runner if the force is 200 newtons and the distance is 30 meters?

• 4000 joules

• 5000 joules

• 6000 joules

• 7000 joules

How do you express the unit of work in terms of force and distance?

• Newton per meter

• Newton times meter

• Meter per newton

• Meter times newton

In the second example, how much work is done if John uses 8 newtons of force to move a sled 2 meters?

• 12 joules

• 14 joules

• 16 joules

• 18 joules

What is the work done if a force of 8 newtons moves an object 2 meters?

• 10 joules

• 14 joules

• 16 joules

• 12 joules

In the third example, what force is needed to move a chair 10 meters if 500 joules of work is done?

• 50 newtons

• 60 newtons

• 70 newtons

• 40 newtons

How do you calculate force if work and distance are known?

• Distance divided by work

• Distance times work

• Work divided by distance

• Work times distance

In the final example, what is the distance moved by a bike if 600 joules of work is done with a force of 40 newtons?

• 18 meters

• 15 meters

• 12 meters

• 10 meters

How do you find the distance if work and force are given?

• Work times force

• Force times work

• Work divided by force

• Force divided by work

What is the SI unit for work?

• Newton

• Watt

• Meter

• Joule
