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?
To calculate 200 J of work in 20 seconds would be to calculate the power. You would use the equation power equals work divided by time. This gives you 10 W of power.
How do you calculate power?
Power=work over time = watts(W)
What equation is used to calculate work?
Work = Force * work=Force x Distance
How much power does it take to raise an object weighing 103 N a distance of 16.0 m in 48.0 s?
Calculate this in two steps. 1. Calculate the total work required. Reminder: work = force x distance. 2. Divide the work by the time to get the power.
How are energy distance mass and acceleration related?
They are often used to calculate the energy used in a specific process involving work.
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
How do you calculate 200j of work done in 20s?
To calculate 200 J of work in 20 seconds would be to calculate the power. You would use the equation power equals work divided by time. This gives you 10 W of power.
How do you calculate power?
Power=work over time = watts(W)
Are Kinematics equations only used by physicists and people who work at NASA.?
False.
What term is defined as mathmatical equations based on rules of physics?
work = force x distance time = distance : time power = work : time force = ?
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).
What is used to calculate mechanical efficiency?
work
What equation is used to calculate work?
Work = Force * work=Force x Distance
How are calculus and electrical engineering related?
I wish I had a more general answer, but I can give a specific example. In order to work with circuits, differential equations (an area of calculus) must be used to understand and study the relationships between current, voltage, resistance, power, and work.
How do you work out if a plane will fly?
You calculate the overall weight, wing area and engine power.
