What happens to kinetic energy when the speed of an object increases?
It increases
When a bow is drawn, what type of energy is primarily stored in the bow?
Elastic Potential Energy
What is the main reason for the occurrence of seasons on Earth?
Earth's axial tilt and its orbit around the sun.
How long does it take for Earth to complete one full revolution around the Sun?
365 days
Summer Solstice
What happens to gravitational potential energy as an object falls?
It decreases
What type of energy is stored in food?
Chemical Potential Energy
During which season is the Northern Hemisphere tilted toward the Sun?
Summer
What is the angle of Earth's axial tilt?
23.5 degrees
What phenomenon occurs when the Sun is directly overhead at the equator?
Equinox
Which energy conversion occurs when a candle burns?
Chemical to Thermal
Which energy transformation occurs when a pendulum swings upward?
Kinetic to gravitational potential
What is a common MISCONCEPTION about the cause of the seasons?
Seasons are caused by Earth's distance from the Sun.
If Earth's axis were not tilted, what would be the result?
There would be no seasons.
What is true about the Southern Hemisphere during June?
It experiences winter
How is kinetic energy related to mass?
It increases with increasing mass
What type of energy is primarily involved when a rock at the top of a hill rolls down?
Gravitational Potential to Kinetic
When the Northern Hemisphere is experiencing winter, what season is the Southern Hemisphere experiencing?
Summer
How does the tilt of Earth's axis affect the length of day and night?
It causes longer days in the summer and shorter nights.
What occurs during an equinox?
Day and night are approximately equal in length.
When a car brakes to a stop, its kinetic energy is mainly converted into what type of energy?
Thermal
In what way is gravitational potential energy different from kinetic energy?
Only Kinetic energy depends on speed
How does Earth's revolution around the Sun contribute to seasonal changes?
By changing the angle of sunlight reaching different parts of Earth.
Which hemisphere experiences summer when the Southern Hemisphere is TILTED AWAY from the Sun?
Northern Hemisphere
Why is it warmer at the equator that at the poles?
The Sun's rays hit the equator more directly.
