Work and Power

What is the formula for calculating Work?

• Work (W) = Force (F) × Distance (d)

• Work (W) = Force (F) + Distance (d)

• Work (W) = Force (F) / Distance (d)

• Work (W) = Force (F) - Distance (d)

What is the significance of the unit Watt?

• One Watt is defined as one Joule of work done per second.

• One Watt is equal to one Newton of force applied over one meter.

• One Watt is the power required to lift one kilogram against gravity for one second.

• One Watt is the energy consumed by a device operating at one volt and one ampere.

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

• Work is inversely proportional to Force and Distance.

• Work is directly proportional to both Force and Distance.

• Work is independent of Force and Distance.

• Work is only dependent on Distance.

How do you calculate Force using Work and Distance?

• Force (F) = Work (W) / Distance (d)

• Force (F) = Distance (d) / Work (W)

• Force (F) = Work (W) + Distance (d)

• Force (F) = Work (W) - Distance (d)

What is Power?

• The ability to do work or cause change.

• The rate at which work is done or energy is transferred.

• A measure of energy consumption over time.

• The total amount of work done in a system.

What is Work?

• Work is the product of force and distance.

• Work is the sum of energy and power.

• Work is the rate of doing energy.

• Work is the total amount of force applied.

What is the formula for calculating Power?

• Power (P) = Work (W) / Time (t)

• Power (P) = Force (F) x Distance (d)

• Power (P) = Mass (m) x Acceleration (a)

• Power (P) = Energy (E) / Distance (d)

What is Resistance Force?

• A force that accelerates an object in motion.

• A force that opposes the motion of an object.

• A force that increases the speed of an object.

• A force that changes the direction of an object.

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

• 10 N

• 12 N

• 15 N

• 20 N

What is the unit of Work?

• Pascals (Pa)

• Joules (J)

• Watts (W)

• Newtons (N)
