What are three ways that an object can store energy?
1. By movement, kinetic energy 2. By raising its temperature, thermal energy 3. By raising it above earth's surface, potential gravitational energy
At what altitude above the earth surface the value of 'g' reduces to half of its value at the surface?
at about 9km above the surface of the sea.
Why is the gravitational potential energy of an object 1 meter above the Moon's surface less than its potential energy 1 meter above Earth's surface?
There is less gravity on the Moon. Gravitational potential energy can be calculated by multiplying weight x height, or the equivalent mass x gravity x height.
What type of surface on earth would transfer the most thermal energy to the air above it?
A highly reflective and/or conductive surface. Asphalt and sand both reflect, and thereby transfer more heat to the air above it (this is why they tend to produce mirages)
Can chemical energy be converted to gravitational potential energy?
By using chemicals in a rocket engine to raise a vehicle high above the earth's surface, the vehicle will gain gravitational potential energy. It will also gain kinetic energy, depending on what trajectory it follows
What energy resources are found above the earths surface?
Solar, wind, water
What potential energy occurs because an object is above the surface of the earth?
That is called gravitational potential energy.
What is potential energy in foot pound of 100 pound drum hanging 10 feet above the surface of earth with reffence to the surface of earth?
1000
What causes the Sun's energy in Earth's atmosphere to produce winds?
When the act of the Earth's surface absorbing the sun's energy, it turns light into heat. The heat on the Earth's surface warms the air above it causing the air over the equator to get warmer than the surface air.
What potential energy depends on height is called?
Gravitational potential energy - it depends on the distance from the centre of gravity, so on Earth it depends on the height above the Earth's surface
Why is the gravitational potential energy of an objects 1 meter above the moons surface less than its potential energy 1 meter above Earths surface?
because the value of gravitational force of earth is greater than that of moon.
What is right above the epicenter of the earth's surface?
The Earth's surface has no arguable epicenter.
Where is a meteoroid when it is 75 km above earth's surface?
When a meteoroid is 75 km above earth's surface, it is within the troposphere.
What is the layer above the Earth's surface?
the layer above the earth is the troposphere
Where in the Earth would you weigh the most 5km above the surface of the Earth 5km below the surface of the Earth at the center of the Earth on the Earths surface?
You would weigh the most on the surface, where the most gravitational energy is below you.As you enter the Earth, gravitational force is also exerted from the mass above, meaning that when you reach the center, the gravitational force will be equal from all directions, leaving you weightless.As you depart the surface of the Earth, you will lose weight as the gravitational force weakens with distance.
Energy which is a result of an object's height above the earth is?
Energy which is a result of an object's height above the earth is potential energy.
What are three ways that an object can store energy?
1. By movement, kinetic energy 2. By raising its temperature, thermal energy 3. By raising it above earth's surface, potential gravitational energy
