At which point in the image, would the skateboarder have the greatest Kinetic Energy & Why?

Answer 1

To determine at which point the skateboarder would have the greatest kinetic energy in the image, we need to consider the factors that affect kinetic energy. Kinetic energy is given by the equation KE = 1/2 * m * v^2, where m is the mass of the object (skateboarder) and v is its velocity.

Based on the image, the skateboarder is seen performing a jump on a ramp. The skateboarder's velocity and thus kinetic energy will vary at different points in the jump.

The greatest kinetic energy will occur at the highest point of the jump. This is because as the skater goes up the ramp, their potential energy is converted into kinetic energy. At the highest point, the skateboarder will have reached their maximum potential energy and would have no more potential energy left to convert. Therefore, all the energy will be in the form of kinetic energy, resulting in the greatest value at that moment.

It is important to note that once the skateboarder starts descending from the highest point and gravity starts to act upon them, their potential energy will increase again while their kinetic energy decreases.
