As shown below, an object with a mass of 5kg is moving at a speed of 10 m/s. another object with the mass of 10kg is moving at the speed of 5 m/s.
which of the object have a higher kinetic energy
The formula for kinetic energy (KE) is KE = 1/2 * mass * velocity^2.
Calculating the kinetic energy for the first object:
KE1 = 1/2 * 5kg * (10 m/s)^2
KE1 = 1/2 * 5kg * 100 m^2/s^2
KE1 = 250 Joules
Calculating the kinetic energy for the second object:
KE2 = 1/2 * 10kg * (5 m/s)^2
KE2 = 1/2 * 10kg * 25 m^2/s^2
KE2 = 125 Joules
Comparing the values, we find that the first object with a mass of 5kg and a speed of 10 m/s has a higher kinetic energy of 250 Joules.
To determine which object has a higher kinetic energy, we can use the formula for kinetic energy:
Kinetic energy (KE) = 1/2 * mass * velocity^2
For the first object:
Mass = 5 kg
Velocity = 10 m/s
KE1 = 1/2 * 5 kg * (10 m/s)^2
For the second object:
Mass = 10 kg
Velocity = 5 m/s
KE2 = 1/2 * 10 kg * (5 m/s)^2
To compare the kinetic energies of the two objects, we can calculate the values:
KE1 = 1/2 * 5 kg * 100 m^2/s^2 = 250 Joules
KE2 = 1/2 * 10 kg * 25 m^2/s^2 = 125 Joules
Comparing the values, we find that the first object, with a mass of 5 kg and moving at a speed of 10 m/s, has a higher kinetic energy of 250 Joules.
To determine which object has a higher kinetic energy, we need to calculate the kinetic energy for each object using the formula:
Kinetic Energy (KE) = 1/2 * mass * velocity^2
For the first object with a mass of 5 kg and a speed of 10 m/s:
KE_1 = 1/2 * 5 kg * (10 m/s)^2 = 1/2 * 5 * 100 = 250 joules
And for the second object with a mass of 10 kg and a speed of 5 m/s:
KE_2 = 1/2 * 10 kg * (5 m/s)^2 = 1/2 * 10 * 25 = 250 joules
As we can see, both objects have the same kinetic energy of 250 joules. Therefore, both objects have the same amount of kinetic energy, despite having different masses and speeds.
