Just remember 1 or 2 formulae..
Kinetic energy=.5mv^2
potential energy=mgh......(h is very smaller than Radius of earth)
Potential energy in spring=.5K(x^2)
.
Do not forget!! this 1
"net work done by the body=change in kinetic energy"
energy conservation should be applied very carefully!

How do you calculate 200j of work done in 20s?
Work done is calculated using the formula: Work = Force x Distance. If you have the result in joules and the time taken, you can calculate the power using the formula: Power = Work / Time. So, you can determine the power required to do 200j of work in 20s.
How do you calculate work with power and time?
Work can be calculated by multiplying power by time. The formula is: Work = power × time. This equation is derived from the definition of power, which is the rate at which work is done over time.
What is the average power formula and how is it used in calculating power consumption?
The average power formula is P W/t, where P represents power, W represents work done, and t represents time. This formula is used to calculate the average amount of power consumed over a period of time by dividing the work done by the time taken to do that work. It helps in determining the rate at which energy is used or transferred in a system.
A person weighing 600N gets on an elevator the elevator lifts the person 6m in 10 seconds how much power was used?
Power is calculated by the formula Power = Work / Time. First, calculate the work done, which is Work = Force x Distance. Work = 600N x 6m = 3600 J. Substituting into the power formula, Power = 3600 J / 10 s = 360 W. Thus, 360 watts of power was used to lift the person.
What is the unit of power and what is the equation for caculating power?
Power refers to energy transfer per unit time; the SI unit of power is the watt; 1 watt is 1 joule/second. There are several equations that involve power; the most basic one, of course, is based on the definition of power: power = energy / time There are several other equations for power; for example, the following equations are commonly used, specifically in electrical circuits: P = IV P = I2R P = V2/R ... where P = power, I = current, V = voltage, R = resistance.
Which equation can be used to calculate power?
There are several equations for power. For example, the definition of power: P = work/time Specifically for electricity, the following equations are often used: P = I2R P = V2/R
The formula work and time is used to calculate what?
Power = Work/Time Time = Work/Power Work = Power * Time See related links for a power calculator. Insert work and time to calculate power.
What is the meaning of horsepower?
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. A few equations to help you calculate horsepower: Power = Work / Time Power = (Force x Distance) / Time
What power was used if it took 2s?
We would need more information to determine the power used. Power is calculated by the formula: Power = Work / Time. If you provide the amount of work done within the 2 seconds, then we can calculate the power used.
How do you calculate 200j of work done in 20s?

How do you find power from force distance time and work?
Power = (work) divided by (time) If you don't know the amount of work, you can calculate it. Work = (force) times (distance).
