What else can I help you with?
Ignoring air resistance what is the minimum initial speed a projectile must have at the Earths surface if the projectile is to escape the Earths gravitational pull?
The minimum initial speed for a projectile to escape Earth's gravitational pull (escape velocity) is about 11.2 km/s. This speed is independent of the mass of the projectile and is based on the balance between the projectile's kinetic energy and gravitational potential energy. Any speed greater than the escape velocity will allow the projectile to escape Earth's gravitational pull.
Explain What is the Orbital Energy and what is the Escape Velocity?
Orbital energy is that amount of energy to keep a spacecraft or satellite in orbit around the earth. If the object fails to maintain this amount of energy, its orbit will get smaller and smaller until the object falls to earth. Escape velocity is that amount of speed required for an object to escape the earth's gravitational hold. Notice how you can't jump into outer space. It's because your legs can't produce enough power to achieve escape velocity.
Would a spacecraft need as much fuel to escape from the moons gravity as it would to escape from the earths?
Escape velocity for the moon is a little over 5000 miles per hour. For the earth it is about 25,000 miles per hour. So the moon requires a fifth of the energy required to escape the earth.
How is the escape velocity equation derived?
The escape velocity equation is derived by setting the kinetic energy of an object equal to the gravitational potential energy at the surface of a planet. By equating these two energies, we can solve for the velocity needed for an object to escape the planet's gravitational pull. The equation is derived using principles of energy conservation and Newton's laws of motion.
What is the escape velocity?
In physics, escape velocity is the speed where the kinetic energy of an object is equal to the magnitude of its gravitational potential energy.The Earths escape velocity is about 11.2 kilometers per secondTo escape the solar system from Earth requires an escape velocity of about 42.1 kilometers per second.

What is the total amount of kinetic energy in an object?
The kinetic energy in an object is EK=mcV where V is the velocity, a vector.
What does the amount of kinetic energy and object has depend on?
The amount of kinetic energy an object has depends on its mass and velocity. The kinetic energy of an object increases as its mass or velocity increases. Mathematically, kinetic energy is calculated as 1/2 times the mass of the object times the square of its velocity.
The amount of kinetic energy an object has depends upon what factors?
The amount of kinetic energy an object has depends on its mass and its velocity. The kinetic energy of an object increases with both its mass and its velocity.
What is the derivation of the escape velocity?
The escape velocity is derived from the gravitational potential energy and kinetic energy equations, taking into account the mass of the object and the distance from the center of the gravitational field. It represents the minimum velocity needed for an object to break free from the gravitational pull of a celestial body, such as a planet or a star.
What is the amount of heat energy in the earths atmosphere referred to as?
the altitude
How can two objects have the same amount of kinetic energy?
Two objects can have the same amount of kinetic energy if they have the same mass and velocity. Kinetic energy is given by the formula KE = 0.5 * mass * velocity^2, so if both objects have the same mass and velocity, they will have the same kinetic energy.
What are the amount of kinetic energy an object has depends on its?
The amount of kinetic energy an object has depends on its mass and velocity. Kinetic energy is calculated using the formula KE = 0.5 * mass * velocity^2, which shows that both mass and velocity play a role in determining the total kinetic energy of an object.
