What else can I help you with?
What falls but never hit the ground?
The temperature.
Will the object that is dropped hit the ground before an object that is that it is thrown horizontally from the same height?
No, both objects will hit the ground at the same time, assuming air resistance is negligible. This is because the time it takes for an object to fall is only influenced by its initial vertical velocity and the acceleration due to gravity, not its horizontal motion.
How does weight and air resistance affect how fast an object falls?
Weight has nothing to do with how fast things fall, only wind resistance. Take two 16 ounce soda bottles, open one drink eight ounces. The unopened bottle is twice as heavy as the opened bottle. Close the bottle you just drank half of and drop them at the same time from a tall building, they will hit the ground at the same time. That is because gravity is a constant and the velocity of any falling object is 9.8 meters per second/per second. Acceleration is the same for all objects at m/s^2 (32.2 ft/s^2 or 22 mph) for each second of its descent. Thus, ignoring air resistance an object starting from rest will attain a velocity of 9.81 m/s after one second, 19.62 m/s after two seconds, and so on. If you are wondering why a hammer hit the ground before a feather, look at it's aerodynamic qualities, it has nothing to do with its weight. Air resitance depends on the coefficient of drag and has nothing to do with weight.
Object leave ground with same velocity as when it hit ground?
The velocity of an object that leaves the ground is the same as the velocity when it hits the ground on the condition that it is only acted on by gravity, that it lands on an equivalent surface to one that it left in terms of potential energy (altitude]. In a closed system energy must be conserved so an object that leaves the ground with a certain quantity of kinetic energy must hit the ground with the same quantity of kinetic energy as gravity its self which also means that given the surface it lands on is the same in potential energy as the surface it left, the object must have the same velocity as E mv^2/2. Of course the object in real life is subject to friction and various contributing factors so it is only true in an ideal case that the object returns to the ground with the same velocity that it left the ground.
Is it true an object that will hit the ground before an object that is thrown horizontally?
No, objects fall at the same rate regardless of their horizontal velocity. Both objects would hit the ground at the same time if dropped from the same height.
Why does the shape of an object falling affects the time that it takes to hit the ground?
It's all about the air resistance that the object receives as it falls in an atmosphere. The air has to move around the object as it falls, if it's allowed to move smoothly aroundyam object by the objects shape then the force of the air resistance is lower. This allows the object to fall faster.
What falls but never hit the ground?
The temperature.
True or false. A 100 lb object and a 2 lb object are dropped from the same height The 100lb object will hit the ground first?
If both objects have similar air resistance factors, they will both hit the ground together.
How fast does a basketball ushally hit the ground?
Depends on how high it was dropped from.
An object with a mass of 8 kg is dropped and takes 2 s to hit the ground. Then another object with a mass of 16 kg is dropped from the same point. How long does it take to hit the ground?
2s
What falls faster a tennis ball or soccer ball?
it would hit the ground if there was one to hit
How do monorails move so fast?
they use magnets so it doesn't hit the ground
What do you do when you hit a ground ball towards an infielder and are running to first base?
Run as fast as you can.
