Question

why would the pendulum go higher than its starting position if we give it some speed, instead of just dropping it?

because the force of gravity is not the only force acting on the pendulum in this case, which can affect its energy

all of the above

because by pushing it we are doing work on it and increasing its energy

because by giving it some speed, we are adding some kinetic energy along with the gpe it already has

Explanation:

• Giving the pendulum speed adds kinetic energy (KE) to its initial gravitational potential energy (GPE), increasing total energy.
• Pushing it does work, which transfers energy to the pendulum.
• While gravity acts, the added energy (from pushing/speed) allows it to reach a higher position than the starting point. All options contribute to the explanation.

Answer:

All of the above
