What else can I help you with?
If you dropped a 6 inch diameter 20 pound ball and a 2 inch diameter 20 pound ball which would hit the ground first?
They will land at the same time, since the acceleration due to gravity is exactly the same for any object of any mass on Earth, at approximately 9.8 m.s-2
How does a plane make any ground when flying against the movement of the earth when the earth spins faster than a plane can fly?
The plane and every object on Earth is moving relative to the the planet, we just don't notice. When the plane is travelling against the motion of the Earth's spin, it seems like it is travelling forwards, but from space it can be seen that it is travelling backwards.
What is a ground mat?
the earthing mat on the earth
How fast do objects fall in mph?
It depends on how far they've been falling and how they started falling. A bullet shot out of a gun aimed straight downward will travel faster than a ball dropped from the same height. And the speed will not remain constant. It will accelarate at a rate of 32 ft/sec2 until it reaches a terminal velocity due to friction. In other words, it will get faster as it gets closer to the earth.
How do you find the weight of a suitcase having a mass of 72kg exerts the pressure of 85Pa on the ground?
If it has a mass of 72 kg, then its weight on earth is 705.6 newtons (about 158.7 pounds). Its size, shape, color, fabric, contents, or the pressure it exerts on the ground don't matter. Consider this: If you set the suitcase down on its bottom, on one side, or on one end, its pressure on the ground would be different in each case, but its weight would not change.
Which item will drop faster?
objects dropped exactly at the same moment will hit the ground (on earth) at exactly the same moment.
Would feather and a nail reach the ground at the same time?
No, a feather and a nail would not reach the ground at the same time if dropped at the same height in a vacuum. This is because the feather experiences more air resistance, slowing its fall compared to the nail which falls faster due to its higher mass.
Which will fall faster a bullet dropped from a height 1' or a bullet shot from a rifle at a height of 1'?
As long as the barrel is precisely level with the ground, gravity will pull them to the Earth at the same rate.
If you drop a penny and a text book at the sametime. which one will hit the ground first?
If a penny and a text book were dropped in a vacuum then they will both hit the ground at the same time. This refers to Newton's laws. If they are dropped at the same time on earth then the text book would hit the ground first.
What would happen if you dropped a hammer and a feather here on earth?
The hammer would fall faster than the feather due to gravity, regardless of air resistance. In the absence of air resistance, both would hit the ground at the same time in a vacuum, as demonstrated in a vacuum chamber experiment on the Moon by astronaut David Scott in 1971.
Why weres the bombs dropped on Hiroshima and Nagasaki rigged to blow up before they hit the ground?
Because they were so strong, those would break the earth crust.
What would happen if the same objects are dropped under different gravitational conditions?
If the same objects are dropped under different gravitational conditions, they will fall at different rates depending on the strength of the gravitational force. For example, objects will fall faster when dropped on Earth compared to the Moon due to Earth's stronger gravitational pull. The acceleration due to gravity, as well as the resulting speed and impact when the object hits the ground, will vary based on the gravitational conditions.
If the earth spins faster would the moon go faster around the earth?
No. The speed of the moon's orbit does not depend on Earth's spin; it depends on Earth's mass. However, a faster spin on Earth's part would make the moon appear to move across the sky faster, as it would for the sun and stars.
If the earth rotated faster would time go faster?
No.
Which is the force that pulls a ball to the ground after being dropped?
The force that pulls a ball to the ground after being dropped is gravity. Gravity is the natural force of attraction between two objects with mass, in this case, the ball and the Earth.
Why do object fall to the ground when dropped?
Objects fall to the ground when dropped due to the force of gravity pulling them downwards. Gravity is a natural force that attracts all objects with mass towards each other, causing things to fall towards the center of the Earth.
What will happen to a stone dropped from the roof of a single story building to the surface of the earth?
The stone will accelerate towards the Earth due to gravity until it reaches its terminal velocity. Upon impact with the Earth's surface, the stone will experience a sudden deceleration and come to a stop.
