No they don't. Without air resistance, objects fall with constant
acceleration.
On Earth, the acceleration is 9.8 m/s² ... the speed of a falling object
at any time is 9.8 m/s faster than it was 1 second earlier.
Answer:
Weather and erosion
Explanation:
Thats what makes sediment rocks sediment rocks
Answer:
The pendulum only has potential energy.
Explanation:
A pendulum is a weight that is tied to a rope and is also suspended with a pivot and that can swing freely. Said pendulum moves at an angle of 30 degrees. Then he is released. The pendulum moves with a constant amplitude. In this way, it reaches the maximum amplitude when its angle is 30 degrees. The angles mentioned in the exercise are the extremes. At each point, the total energy is conserved. Total energy is defined as the sum of the kinetic energies plus the potential energy. The kinetic energy of the pendulum is equal to zero in the extreme positions, therefore, only the total energy is equal to the potential energy.
If you dont open the freezer everything will stay contained and frozen.
It takes 7.0s for a piece of wood to be falling from a tall building in the velocity of 68.6 m/s
<u>Explanation:</u>
v = u + at
68.6 ms^-1 = 0 ms^-1 + (9.8 ms^-2 x t)
t = 68.6 ms^-1 / 9.8 ms^-2
t = 7.0s
It takes 7.0s for a piece of wood to be falling from a tall building in the velocity of 68.6 m/s
