Velocity is the rate at which an object travels. v = "distance"/"time" = d/t. The units of velocity are metres per second (m/s). Acceleration is the rate at which an object changes its velocity. a = v/t. The units of acceleration are metres per second squared ("m·s"^"-2 ...
- How are force and power related? - SocraticPower is work per unit time. Work is force through a distance. In this way, power and force can be related. Power is work per unit time:
- How do I use the formula P (in) = pQgh? + Example - SocraticExample. Calculate the power theoretically available from water flowing at a rate of 1m3/s with a fall of 100m: P th = (1000kg/m3) ⋅ (1m3/s) ⋅ (9.81m/s2) ⋅ (100m) P th = 981000W. P th = 981kW. You use the formula to calculate the theoretical power available from falling water. The following is summarized from the following webpage ...
- How is electric power related to electrical energy? | SocraticAnswer link. P = E/t electrical power is the amount of electrical energy transferred in a certain amount of time. the SI unit used to measure power is the watt (W). 1 watt is the same as 1 joule of energy transferred per second. when a second passes, and 1 joule is transferred per second, 1 joule will be transferred in that second. this means ...
- Electric Power - Physics - SocraticIt is a unit of energy equal to 1,000 watt-hours, or 3.6 megajoules. If the energy is being transmitted or used at a constant power over a period of time, the total energy in kilowatt-hours is the product of the power in kilowatts and the time in hours. It is commonly used as a billing unit for energy delivered to consumers by electric utilities.
