What is the word that causes all objects to fall at different speeds?
In the absence of air, all objects fall with the same acceleration. That means that at the same time after the drop, all objects are moving at the same speed.
What term describe an apparent change in frequency of sound waves of rapidly moving?
Doppler Shift. It occurs in electromagnetic radiation too, though is really only significant at extremely high speeds such as the recession-rate of galaxies.
When does the Doppler effect happen?
The doppler effect happens when the source of a sound is moving. When it is moving towards you, it sounds louder and can have a different pitch and when the source is moving away, its a quieter more "far-off" sound. This is because when the source is moving, the sound waves are getting compressed in front of it due to relative velocity. Once the sound wave is made, it's speed is independent of its source. This is also how a sonic boom happens. At super sonic speeds, the sound barrier is broken which is the build up of all the sound waves created.
Do different objects fall at different speeds?
Air resistance
Why does objects fall in different speeds?
all objects fall at the same speed because i like ponies
Why the planets seemed to move at different speeds?
The gravitational pull of other objects in space affect all
How does air resistance affect the velocity of falling objects?
Slows an object down or speeds one up.
What is the word that causes all objects to fall at different speeds?
In the absence of air, all objects fall with the same acceleration. That means that at the same time after the drop, all objects are moving at the same speed.
What does EMc2 mean in spanish?
This is not Spanish, this is the equation that describes the behavior of objects moving at speeds comparable with the speed of Light: E = M c2

What a moving object in outer space slow down?
Most objects in outer space are moving under the gravitational attraction of other galaxies or galactic clusters. The attractive force speeds them up rather than slows them down.
What is a hole formed when two objects in space collide?
If two objects in space collide the result depends on both relative sizes and speeds of the objects.if the objects are moving with little difference in speed, they will simply stick togetherif the objects are of similar size and moving at high speed, they with both shatter into smaller piecesif the objects are of much different size and moving at high speeds, the smaller one will punch a hole in the larger one called a craterwhen an object about the size of Mars collided with the early Earth shortly after the Earth first developed a solid crust, both objects completely remelted and a spray of mixed Earth's mantle and the object entered orbit about the Earth and when it solidified became the Moon, no crater was left on Earth as it melted completely then resolidified tooetc.
Can two people be moving at the different speeds and have the same kinetic energy?
Sure. Kinetic energy depends on both mass and speed. So two objects could have different speeds, but if their masses are also different by just the right amount, their KE's could be equal.

What happens when a moving object speeds up slows down or changes directions is it acelleration?
what happens when a moving object speeds up,slows down,or changes direction?
