When the ball bounces up it has kinetic energy.But before it falls it has potential energy, and then as it falls has kinetic energy again. The ones used the most is kinetic.
1. Applying more force and energy, speeding up
2. Releasing potential and kinetic energy by going down a slope, speeding up
3. Applying less force to slow down and let friction overcome the bicyclist
Answer:
Three terms in planetary science sound similar but have different meanings.Fill in the blanks below with the correct term. Important: Spelling matters! Use only lowercase! a. A solar eclipse occurs when the Moon passes across the disk of the Sun. b. An ellipse describes the shape of a planetary orbit about the Sun.c. The ecliptic describes the path of the Sun as seen against the background stars.
Explanation:
When the moon places between the Earth and the Sun, a solar eclipse occurs. The moon is capable to hide the solar disk, even with the sun being 400 times bigger than the moon but the moon is 400 times closer to the Earth than the sun.
Kepler's first law establishes that all the planets revolve around the Sun in an ellipse orbit, with the sun in one of the focus.
The ecliptic is the apparent path that the sun has in the celestial sphere as a consequence of the daily movement of the Earth around its axis
