Question 26(1 mark)SavedTex kicks a goal! The football wouldonly have gravitational potential energyonly have stored energyhave both gravitational potential and kinetic energyonly have kinetic energy
Solution
The football would have both gravitational potential and kinetic energy.
Here's why:
-
Gravitational Potential Energy: When Tex kicks the football, it goes up into the air. At its highest point, the football has maximum gravitational potential energy because it has the potential to fall down due to gravity.
-
Kinetic Energy: When the football is moving, either going up into the air or coming down, it has kinetic energy. This is the energy of motion. The faster the football moves, the more kinetic energy it has.
So, the football has both gravitational potential energy and kinetic energy at different points in its trajectory.
