### What type of energy does a parked car have?

Explanation:
A parked car has potential energy due to its position. This type of energy is stored based on the object's position relative to other objects, using gravitational force as a factor. For a car parked on a hill, the higher it is up the hill, the greater its potential gravitational energy. The energy could be converted into kinetic energy (the energy of motion) if the car starts to move downhill. Therefore, potential energy is the most accurate description for a stationary car in a specific context like being on an incline.

### Which form of energy is possessed by a flying bird?

Explanation:
A flying bird primarily possesses kinetic energy because this form of energy is associated with motion. As the bird flies, its velocity converts the potential energy stored in its muscles into kinetic energy. The faster the bird flies, the more kinetic energy it generates. This energy enables the bird to continue moving and maneuver in the air, overcoming air resistance and gravitational pull through the expenditure of energy in the form of movement.

### What energy transformation occurs when a bow is drawn?

Explanation:
When a bow is drawn, potential energy is stored in the stretched limbs of the bow. The mechanical energy exerted by pulling the bowstring back is converted into potential energy as the bow is held in tension. Once the bowstring is released, this potential energy is rapidly converted back into kinetic energy as the bow returns to its original shape and the arrow is propelled forward with significant force. This demonstrates the transformation of energy from potential to kinetic within the mechanics of archery.

### Where is potential energy highest in a swung pendulum?

Explanation:
In a swinging pendulum, potential energy is highest at the top of the swing, where the pendulum's speed is at its lowest. At this point, the pendulum has maximum potential energy due to its elevated position against gravity. As the pendulum begins its descent, this potential energy is converted into kinetic energy, which increases as the pendulum speeds up reaching the lowest point. Thus, the maximum potential energy at the top is a result of its height and gravitational potential.

### What type of energy does a compressed spring hold?

Explanation:
A compressed spring holds potential energy, which is stored due to its position. When the spring is compressed, mechanical work is done against the spring’s natural force, which stores energy in the form of elastic potential energy. This energy is retained until the force compressing the spring is removed, at which point the stored energy is converted back to kinetic energy as the spring returns to its original shape, pushing against whatever compressed it.

### Which energy is primarily used by a cyclist climbing a hill?

Explanation:
When a cyclist climbs a hill, they are primarily using kinetic energy to propel the bicycle forward; however, as they reach higher elevation, the energy usage shifts towards gaining potential energy due to increased altitude. The kinetic energy from pedaling is converted into potential energy, which could potentially be converted back into kinetic energy on a downhill path. Therefore, the cyclist's effort in climbing a hill translates directly into potential energy accumulation in relation to gravity.

### What kind of energy does water behind a dam possess?

Explanation:
The water stored behind a dam possesses potential energy due to its elevated position relative to the base of the dam. This gravitational potential energy is significant because of the large volume of water and the height from which it can potentially fall. When the water is released, this potential energy is converted into kinetic energy as the water moves downward through the dam's turbines, generating electricity as a result of this energy transformation.
8.

### Which form of energy is demonstrated by a stretched rubber band?

Explanation:
A stretched rubber band exhibits potential energy. When the rubber band is stretched, it stores elastic potential energy based on how much it is deformed from its natural state. This stored energy is a result of the work done in stretching it, and this energy can be released as kinetic energy when the band snaps back to its original shape, propelling any attached objects or itself forward.
9.

### What kind of energy transformation occurs when brakes are applied to a moving car?

Explanation:
When brakes are applied to a moving car, the kinetic energy of the car (due to its motion) is transformed into thermal energy. This transformation occurs through friction between the car's brake pads and the wheel or drum. This friction generates heat, effectively converting the motion energy of the car into heat energy, which dissipates into the environment. This process is an example of the conservation of energy where kinetic energy is not lost but converted into another form.
