Kinetic Energy = 1/2 * mass(kg) * Velocity(m/s) squared
KE = 1/2mV^2
KE =1/2(2500 kg)(35 m/s)^2
= 1531250 Joules
better expressed as
1.5 X 10^6 Joules
When the bike is moving at 2 m/s, its kinetic energy is (1/2 m v2) = (5 x 4) = 20 joules.When it's moving at 3 m/s, its kinetic energy is (1/2 m v2) = (5 x 9) = 45 joules.The difference between initial KE and final KE is (45 - 20) = 25 joules.That's how much work you have to do on it in order to increase its KE.
It's the position above the surface Potential Energy: stored energy Kinetic Energy: energy's movement (moving)
KE = 1/2 mass *velocity squared A direct relationship. More mass, and a truck has more mass, and the more kinetic energy if velocities are held equal.
The kinetic energy is one half the mass times the velocity squared KE = 1/2 mv^2 First you cannot mix English and metric units, so you need to convert miles per hour to meters per second and your answer will be in kg m^2/sec^2 or joules 80 mph = 35.76 meters per second KE = 1/2 (80) x (35.76)^2 = 51,151 joules
Are you sure you mean 10 miles per second? That is a speed of 36,000 mph (unless you are referring to the speed of the car relative to the orbit of the earth as the earth orbits the sun, but that is approx 19 miles per second). I think you mean 10 metres per second (as you've used a metric measure for the mass of the car). kinetic energy = ½ × mass × velocity² → KE = ½ × 1500 kg × (10 m/s)² → KE = 75000 kgm²/s² = 75000 Joules = 75 kJ
The object with the mass of 4 kilograms that was lifted at a rate of 3 meters per second would have more kinetic energy. Kinetic energy depends on both mass and velocity, so the increased mass more than compensated for the lower velocity compared to the 2-kilogram object.
The kinetic energy of a ceiling fan depends on its mass and the speed at which it is spinning. The formula for kinetic energy is 0.5 * mass * velocity^2, where mass is in kilograms and velocity is in meters per second. Generally, the kinetic energy of a ceiling fan is relatively low compared to other moving objects.
Kinetic energy is the energy of motion. Your touching finger has mass and is moving some meters per second, so that motion is kenetic energy.
a moving car has kinetic energy which is defined by the equation "Kinetic Energy = (1/2) X Mass (Kilograms) X (Velocity (m/s))2
A moving car has kinetic energy as a result of its motion, as well as potential energy stored in its fuel if it has not been fully converted to kinetic energy yet. Additionally, the car's engine generates mechanical energy used for propulsion.
The kinetic energy of the person can be calculated using the formula: KE = 0.5 * mass * velocity^2. First convert the mass to kilograms (1 gram = 0.001 kg), then plug in the values to find the kinetic energy. The result will be in Joules.
Any moving object has kinetic energy.
Kinetic energy is directly proportional to the square of velocity, so the kinetic energy will increase. If the velocity increases from 20 m/s to 32 m/s, the kinetic energy will increase by a factor of (32/20)^2 = 2.56. Therefore, the kinetic energy will be 4500 Joules * 2.56 = 11520 Joules when the velocity is 32 m/s.
Yes, a plane moving has kinetic energy. Kinetic energy is the energy of motion, and an object in motion, such as a plane flying through the air, possesses kinetic energy.
KE = 1/2 * mass * velocity squared KE = 1/2mV2 KE = 1/2(4 kilograms )(6 m/s )2 = 72 Joules ---------------
A moving ball has kinetic energy, which is energy associated with its motion.
Kinetic energy is the energy of moving things, And a bicycle in use is a moving thing.
