What is the equation for workdone?

• Work done = force x energy transferred

• work done = force x distance x energy transferred

• Work done = force x distance

• Work done = force/distance

What the equation for kinetic energy.

• kinetic energy = mass x 0.5 / speed³

• Kinetic energy = mass x 0.5 x (speed)³

• Kinetic energy = 0.5 x mass x (speed)²

• Kinetic energy = 0.5 x speed x (mass)²

Equation that links: work done , time and power

• Workdone = power x time

• power = work done / time

• power = workdone x time

• power = work done x time³

What equation links: power , energy transferred and time?

• power = energy transferred / time

• power = energy transferred x time

• power = time / energy transferred

What is the equation for gravitational potential energy?

• gravitational potential energy = mass x gravity x height

• gravitational potential energy = mass x gravity x height ²

• gravitational potential energy= mass x 0.5 x gravity x height

The equtation for efficency is?

• efficency = useful output / total input

• efficency = total input / useful output

• efficency = total input x useful output

The equation for charge is?

• current = charge x time

• charge = current x time

• charge = current / time

• charge = time / currrent

What is the equation for potential difference?

• PD = charge x resitance

• PD = current x resitance

• PD = current / resitance

• PD = resitance / current

equation linking : power, PD and current

• Power = PD X current²
