## What is the power of newton?

Definition. A newton is defined as 1 kg⋅m/s2 (it is a derived unit which is defined in terms of the SI base units). One newton is therefore the force needed to accelerate one kilogram of mass at the rate of one metre per second squared in the direction of the applied force.

## What is power and force?

Force is the fundamental result of an interaction between two objects, while power is an expression of energy consumed over time (work), of which force is an element. Force and power can both be described and measured, but a force is an actual physical phenomenon, and power in itself is not.

**What is power in physics and examples?**

Power is the rate at which work is done. The SI unit for power is the watt (W), where 1 watt equals 1 joule/second (1 W=1 J/s). Because work is energy transfer, power is also the rate at which energy is expended. A 60-W light bulb, for example, expends 60 J of energy per second.

**What is power and write its formula?**

Power is defined as the rate of doing work. It is the ratio of the work done(W)and the time taken(t). Power(P)=Time(t)Work(W) The SI unit of power is Watt(W), in the honor of physicist James Watt.

### How do you convert Newtons to power?

One watt is equal to 1 Newton-meter per second (Nm/s). You can multiply the amount of torque in Newton-meters by the rotational speed in order to find the power in watts. Another way to look at power is as a unit of speed (m/s) combined with a unit of force (N).

### Is force equal to power?

Calculating Power Since work is force times displacement (W=F*d), and velocity is displacement over time (v=d/t), power equals force times velocity: P = F*v. More power is seen when the system is both strong in force and fast in velocity.

**How is power calculated?**

Power is equal to work divided by time. In this example, P = 9000 J / 60 s = 150 W . You can also use our power calculator to find work – simply insert the values of power and time.

**What is unit of power in physics?**

WattPower / SI unit

Power (P) is the rate at which energy is transferred or converted. Thus, power equals work divided by time (P = W / t). The SI unit of power is the watt (W), in honor of Scottish inventor James Watt (1736 – 1819).
