Answer/Explanation: Speed and direction can change with time. When you throw a ball into the air, it leaves your hand at a certain speed. As the ball rises, it slows down. Then, as the ball falls back toward the ground, it speeds up again. When the ball hits the ground, its direction of motion changes and it bounces back up into the air.
Cross country, because it has to do with running on your feet
Answer:
1. battery is capable of continuous current, capacitor is not
2. battery maintains a potential, capacitor does not
3. battery stores chemical energy, capacitor stores electric energy
Explanation:
1. battery is capable of continuous current, capacitor is not
This is because the battery maintains a constant current throughout while the capacitor maintains an exponential decaying current.
2. battery maintains a potential, capacitor does not
This is because, the battery has a potential at its terminal due to its emf whereas, the capacitor needs a potential to be applied to its terminals.
3. battery stores chemical energy, capacitor stores electric energy
This is because, the battery converts chemical energy to electrical energy whereas, the capacitor stores electric energy due to its ability to store electric charge.
Assuming the accleration applied was constant, we have
Then the force applied to the ball is given by
