Study Notes

Kinetic Energy

• Defined as the energy of moving objects.
• Examples include a moving car and a running athlete.

Potential Energy

• Energy stored in an object that can be released later.
• Examples include a raised weight or a compressed spring.

Energy Conversion

• Waterfalls illustrate potential energy transforming into kinetic energy as water falls.
• Kinetic energy can convert to potential energy when objects stretch, such as a spring being pulled.

Energy at Different Positions

• A pendulum at the top of its swing has zero kinetic energy and maximum potential energy at that point.
• When an object falls, potential and kinetic energy are equal at the midpoint of its descent, such as a book falling off a table.

Roller Coaster Dynamics

• Maximum kinetic energy in a roller coaster occurs at the bottom of the hills due to gravitational forces.

Kinetic Energy Examples

• Kinetic energy is exemplified by spinning windmill blades powered by wind, illustrating energy transferred from air movement.
• A 20 kg stone traveling at 10 m/s possesses greater kinetic energy than lighter or slower objects.

Positions of Energy

• A frog possesses kinetic energy only at a specific point designated as position Q.
• At position P, an object may have both potential and kinetic energy, such as a ball at different heights during its throw.

Chemical Potential Energy

• Coal and gasoline exemplify chemical potential energy, stored energy that can be harnessed during chemical reactions.

Gravitational Potential Energy

• A ball thrown into the air has maximum gravitational potential energy at its peak height.
• Climbing to the top of a water slide increases gravitational potential energy.

Energy in Objects

• A battery is an example of stored potential energy.
• A compressed spring represents stored potential energy.

Energy Changes During Descent

• As a monkey climbs down a tree, its gravitational potential energy decreases by half if it descends halfway.
