Answer: P = FV becuase all of them are equal in strength.
Explanation: In the straight forward cases where a constant force moves an object at constant velocity, the power is just P = Fv. In a more general case where the velocity is not in the same direction as the force, then the scalar product offorce and velocity must be used. P = Power, F = Force, V = Velocity.

Answer:
The answer is 9.8 N
Explanation:
As we know that the weight of an object is the amount of gravitational force acting on the object in an upward direction if the weight is acting is the downward direction.
The formula of weight:
W = Mass x Gravitational force
W = m x g
Given data:
Mass =1 kg
g = 9.8 ms-2
W = 1kg x 9.8 ms-2 = 9.8 kgms-2 ( 1 kgms-2 = N)
SO,
W = 9.8 N
The toy has an earth weight of 9.8 N.
Power = (voltage) x (current). The motor consumes (12)x(206)=2,472 watts. Some of it is dissipated as heat, but most of it is used to do useful work by turning the engine over to make it start.
Using the formula KE=1/2mv^2
a: The kinetic energy doubles.
b: The kinetic energy quadruples.
c: The kinetic energy is cut in half.
Hopefully it’s clear how the formula can show you this.
