Flashcard Physics

Front

What is the formula for calculating work?

Back

Work (W) = Force (F) × Distance (d) Where work is measured in Joules (J), force in Newtons (N), and distance in meters (m).

Front

What is the unit of power in the International System of Units (SI)?

Back

The unit of power is the Watt (W), which is equivalent to one Joule per second (J/s).

Front

How is power related to work and time?

Back

Power (P) = Work (W) / Time (t) This means that power is the rate at which work is done.

Front

What is elastic potential energy?

Back

Elastic potential energy is the energy stored in elastic materials as the result of their stretching or compressing.

Front

When is elastic potential energy at its maximum?

Back

Elastic potential energy is at its maximum when the elastic material (e.g., a rubber band) is stretched to its limit.

Front

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

Back

Work is done when a force causes an object to move a distance. The greater the force or distance, the more work is done.

Front

If 68 W of power is produced in 18 seconds, how much work is done?

Back

1,224 J

Front

What is the definition of force?

Back

Force is an interaction that causes an object to change its velocity, measured in Newtons (N).

Front

What is the difference between work and energy?

Back

Work is the transfer of energy through force applied over a distance, while energy is the capacity to do work.

Front

What is the formula to calculate force when work and distance are known?

Back

Force (F) = Work (W) / Distance (d) This allows you to find the force applied if you know the work done and the distance moved.
