If there were no air resistance how did the speeds of a feather and a penny compare?
If there was no air resistance and a feather and a penny were dropped from the same height they would both pick up speed by the same amount and they would hit the ground at the same speed and at the same time.
Why does a body exerts more force on ground when it is dropped from a certain height than when it at rest at the ground although in both the cases mass and acceleration is constant See discussion too?
Interesting question. But when the object is at rest the potential energy of the object is 0, on the surface that is. When it is on a height h it's potential energy increase and when it is dropped from that height all that potential energy gets converted to kinetic energy just before hitting the ground. This extra force comes from this kinetic energy.
Why don't all the marbles dropped from a specific height land in the same spot?
If they are dropped in a totally controlled manner then they would land in the same spot. However, if dropped by hand, there will be minor differences in the positions of the hand which will affect the outcomes.
Is height the proper term to use to measure how long a snake is?
Not really. Length is preferable, as height may be confused for the height the snake can raise itself above the ground under its own strength.
When a small egg is dropped onto the piece of one inch foam from which height did the egg fracture but not break?
That sounds like an excellent science experiment! You should totally do that and measure the height in inches or centimeters with a yardstick.
If a cannon fires a cannonball horizontally and you drop a cannonball at the same time which will hit the ground first?
A cannonball fired horizontally and one dropped from the height of the muzzle simultaneous with the shot will hit the ground at the same instant, provided only that the ground under the muzzle and the ground where the shot lands are at the same elevation, i.e. the shot was not fired off the edge of a cliff or into the side of a mountain. To solve this kind of problems, it often helps to separate the movement, or the speed, into vertical and horizontal components. In this case, the vertical component of the speed is the same.
When You Drop An Object From A Certain Height It Takes Time T To Reach The Ground With No Air Resistance. If You Dropped It From Three Times That Height How Long Would It Take To Reach The Ground?
When an object is dropped from a certain height, the time it takes to reach the ground is independent of the height (assuming no air resistance). Therefore, whether you drop the object from three times the initial height or the original height, it will still take the same time (T) to reach the ground.
Which has more kinetic energy a ball dropped from a height of 2m or a same ball dropped at 4m which has more kinetic energy just before it hits the ground?
The ball dropped from 4m height has more kinetic energy just before it hits the ground because it has a higher velocity due to falling from a greater height. Kinetic energy is directly proportional to both mass and the square of velocity, so the ball dropped from 4m height will have more kinetic energy than the one dropped from 2m height.
Will a baseball or basketball reach the ground first?
If dropped from the same height (a few meters), they would appear to hit the ground at the same time, according to the experiments of Galileo. However, this neglects air resistance on the basketball, which will slow it down more and cause it to hit the ground later (very slightly later). The baseball, which has a smaller area and therefore less air resistance, will hit the ground first.
If there were no air resistance how did the speeds of a feather and a penny compare?
If there was no air resistance and a feather and a penny were dropped from the same height they would both pick up speed by the same amount and they would hit the ground at the same speed and at the same time.
If two object of different density are dropped simultaneously which one will hit the ground first?
as done in Galileo's experiment when he dropped a large rock and a feather from a tall tower both hit the ground at the same moment when dropped from the same height.
When Rae dropped a bowling ball from a height of 8 meters At which distance above the ground was the ball most likely moving at the greatest speed?
Still accelerating til it hits earth. ====================================== The height from which she dropped the ball is irrelevant. In any case, the ball was most likely moving at the greatest speed just as it hit the ground. The answer to the question is: zero.
Suppose a baseball and a marble are dropped at the time from the same height which ball would land first?
Discounting any friction with the air, they would both hit the ground at the same time.
Which object, a feather or a hammer, hits the ground first when dropped from the same height?
Both the feather and the hammer will hit the ground at the same time when dropped from the same height in a vacuum. This is due to the principle of gravity, which accelerates all objects at the same rate regardless of their mass.
How does the height a boucny ball is dropped from effect the height it bounces to?
The higher the ball is dropped from, the higher it will bounce back. This is due to potential energy converting to kinetic energy upon impact with the ground, propelling the ball higher when dropped from greater heights. Ultimately, the bounce height depends on factors like gravity, air resistance, and the material of the ball.
Would a bowling ball and a penny hit the ground at the same time if dropped from an equal height?
Yes
A ball was dropped on a top of the building and hits the ground after 15 s. What is the height of the building?
381 metres
