الطاقة: الطاقة الميكانيكية

The video tutorial explains mechanical energy through a simple activity involving a tennis ball. It describes how potential energy is stored when the ball is lifted and transforms into kinetic energy as it falls. The process repeats as the ball bounces, illustrating the conversion between potential and kinetic energy. The tutorial concludes by defining mechanical energy as the sum of potential and kinetic energy and encourages viewers to try the experiment themselves.

What happens to the tennis ball when it is released from head height?

• It moves sideways.

• It floats upwards.

• It falls to the ground and bounces back.

• It stays in the air.

What type of energy is stored when the ball is lifted?

• Kinetic energy

• Potential energy

• Sound energy

• Thermal energy

During the ball's fall, what transformation of energy occurs?

• Sound energy to thermal energy

• Potential energy to kinetic energy

• Kinetic energy to potential energy

• Thermal energy to sound energy

What is the result of combining potential and kinetic energy?

• Sound energy

• Electrical energy

• Mechanical energy

• Thermal energy

What does the video encourage you to do after learning about mechanical energy?
