At the Equator it spins at 1,000 mph.

At 60 degrees N/S, the circumference is half the distance than at the Equator so it inly spins at half the speed ; 500 mph.

At the poles N/S it spins on the spot. 0 mph.

What is the name for the speed a rocket must reach to escape the earth's gravity?

Escape velocity is the speed that a rocket must reach to break free from Earth's gravity and enter space. It is the minimum velocity required for an object to overcome the pull of Earth's gravity.


How do you calculate velocity due to gravity?

The velocity due to gravity can be calculated using the formula: v = gt, where v is the velocity, g is the acceleration due to gravity (approximately 9.81 m/s^2 on Earth), and t is the time in seconds. Simply multiply the acceleration due to gravity by the time to find the velocity.


What is true about an objects fall velocity as it approaches the earth's surface?

As an object falls towards the Earth's surface, its velocity increases due to the acceleration caused by gravity. Near the surface, the object will reach a terminal velocity where the force of air resistance equals the force of gravity, causing the object to fall at a constant speed.


Where is a situation when gravity causes a change in velocity?

One common example is when an object falls freely due to gravity. As the object accelerates towards the Earth, its velocity changes because gravity is constantly acting on it. The object's velocity increases as it falls towards the ground.


What effect does gravity have on velocity?

Gravity changes the velocity of an object that is in "free fall" (that is, one that is only subject to the force of gravity). Near Earth's surface, this change of velocity due to gravity occurs at a rate of 9.8 (meters / second) / second; usually this is written as 9.8 meters/second2.

How do you beat gravity on Earth?

To overcome gravity, you must reach "Escape Velocity" to overcome gravity and escape a planet's orbit.


How using Earth's rotation speed to escape gravity?

Earth's rotation speed doesn't affect the ability to escape Earth's gravity. Escaping Earth's gravity requires reaching a velocity of about 11.2 km/s regardless of Earth's rotation speed. Earth's rotation does provide a slight boost to the velocity required to escape in the direction of the rotation.

What may happen to a rocket which rises from the earth never attains escape velocity?

A rocket that doesn't reach "escape velocity" will be overcome by gravity and will be pulled back down to Earth. Also, rockets which go into orbit have not reached escape velocity. Escape velocity is what is needed to completely leave earth's gravity well.

Describe a situation in which gravity causes a change in velocity why does a change in velocity happen?

When an object is dropped from a height, gravity causes it to accelerate towards the ground. This acceleration leads to a change in velocity as the object's speed increases. The change in velocity occurs because gravity exerts a force on the object, pulling it towards the Earth.
