To calculate power, divide the amount of energy transferred by _____________

Answers

Power is defined in physics as the quantity of energy transported or transformed per unit of time. To calculate power, divide the amount of energy transferred by time.

What is power?

Power is defined in physics as the quantity of energy transported or transformed per unit of time. The watt is the unit of power in the International System of Units, equivalent to one joule per second. Power is also referred to as activity in ancient writings. A scalar quantity is a power.

The formula for power is given as the ratio of energy transferred to the time taken.

Its SI unit is Watt, while the SI units for energy and time are seconds. Therefore, we can write,

Power = Energy transfer / Time taken

Joule = Watt / Second

Hence, To calculate power, divide the amount of energy transferred by time.

What is the kinetic energy of a baseball moving at a speed of 40 m/s if the baseball has mass of 0.15 kg?

Answers

Kinetic Energy = 1/2 Mass (kg) * velocity squared (m/s)

KE = 1/2mV^2

KE = 1/2(0.15 kg)(40 m/s)^2

The answer is 120 joules.

0.5mv^2 > 0.5*0.15*40*40=120J
