Which Term Is Defined As The Rate At Which Work Is Done? Scientists define power as the rate at which work is done, or the rate at which energy is expended. In words: Power is the amount of work done divided by the time it takes to do that work. Which term is the rate
What Is The Kinetic Energy Gained By An Electron? Note that 1 eV is the kinetic energy acquired by an electron or a proton acted upon by a potential difference of 1 volt. The formula for energy in terms of charge and potential difference is E = QV. So 1 eV = (1.6 x 10^-19
What Is The Kinetic Energy Of A 1200 Kg Object? Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared
How Many Joules Can Kill You? An object which impacts a human is considered a 20% chance of being lethal with a head strike if its energy is greater than 80 Joules. How many joules does a bullet have? With this, I can calculate the kinetic energy of one bullet. That’s almost 2000 Joules. If
How Many Joules To Travel 1 Mile? The general rule of thumb is that the average person burns 100 calories per mile of running. (Depressingly, that’s only about 30 m&m’s or one banana). That’s 418 kJ or 116 Watt-hours. How many joules does it take to drive a car? Travelling at 100 kilometres per hour,
How Much Energy In A Calorie? Specifically, a calorie is the amount of energy, or heat, it takes to raise the temperature of 1 gram of water by 1 degree Celsius (1.8 degrees Fahrenheit). One calorie is equal to 4.184 joules, a common unit of energy used in the physical sciences. How much energy is
