One basketball is rolling on the floor.
potential energy – One basketball is rolling on the floor.
kinetic energy – One basketball is rolling on the floor.
potential energy – One basketball is stored on a shelf about 4 feet high.
To calculate the potential energy of the basketball on the shelf, we can use the formula:
Potential energy = mass x g x height
Assuming the mass of the basketball is 0.6 kg and the acceleration due to gravity is 9.8 m/s², and the height is 4 feet which is equivalent to 1.2192 meters, the potential energy can be calculated as follows:
Potential energy = 0.6 kg x 9.8 m/s² x 1.2192 meters
Potential energy = 7.11744 joules
Therefore, the potential energy of the basketball on the shelf is approximately 7.11744 joules.
kinetic energy – One basketball is stored on a shelf about 4 feet high.
Since the basketball is not in motion while on the shelf, its kinetic energy is zero. Kinetic energy is the energy possessed by an object due to its motion, and in this case, the basketball is not moving and therefore has no kinetic energy.
One basketball is rolling on the floor.
To calculate the kinetic energy of the rolling basketball, we can use the formula:
Kinetic energy = 0.5 x mass x velocity²
Assuming the mass of the basketball is still 0.6 kg and the velocity of the rolling basketball is 3 m/s, the kinetic energy can be calculated as follows:
Kinetic energy = 0.5 x 0.6 kg x (3 m/s)²
Kinetic energy = 2.7 joules
Therefore, the kinetic energy of the rolling basketball is approximately 2.7 joules.
The potential energy of an object is the energy that it possesses due to its position or height relative to the ground. In this case, the basketball stored on a shelf about 4 feet high has potential energy because it is elevated from the ground.
The kinetic energy of an object is the energy that it possesses due to its motion. In this case, the basketball rolling on the floor has kinetic energy because it is moving.
To calculate the potential energy of the basketball on the shelf, you can use the formula: potential energy = mass x gravity x height.
First, determine the mass of the basketball. You can generally assume the mass of a basketball to be around 0.6 kg.
Next, determine the acceleration due to gravity, which is approximately 9.8 m/s^2.
Finally, determine the height of the shelf, which is 4 feet or approximately 1.22 meters.
Using these values in the formula, you can calculate the potential energy of the basketball.
To calculate the kinetic energy of the rolling basketball, you can use the formula: kinetic energy = 0.5 x mass x velocity^2.
First, determine the mass of the basketball. Again, you can generally assume the mass of a basketball to be around 0.6 kg.
Next, determine the velocity of the basketball while rolling on the floor. This can be measured using a speedometer or estimated based on the average speed of a basketball being rolled.
Using these values in the formula, you can calculate the kinetic energy of the rolling basketball.
It is worth noting that the potential energy and kinetic energy of an object are not directly related to each other. The potential energy is converted into kinetic energy when the object is allowed to move and vice versa.
