What type of energy exists in a ball sitting on top of a hill?
kinetic energy
When does the skier have the greatest potential energy?
Just standing there, a skier on the top of the mountain has potential energy. If she uses her poles to push-pull before taking off, she's building up a small amount of kinetic energy. If a skier is then moving down the mountain, his movement downward is kinetic energy which increases as his speed increases. If he or she collides with an immovable object while skiing, kinetic energy abruptly ends. If he or she takes off from the top of the mountain and an avalanche happens to hit at the same time, the kinetic energy of the avalanche engulfs the skier and overpowers the lower kinetic energy of the skier. The skier and avalanche become as if one in the kinetic force of the avalanche--until the skier collides with something or is buried, and thus is separated from the avalanche's kinetic energy which continues until the avalanche stops.
A certain pendulum has a potential energy of 20 J when it is at the top of its swing. What is the kinetic energy?
If at the top of the swing the pendulum is STOPPED then it has zero kinetic energy.
In energy transformations when a roller coaster is at the top of the hill the kinetic energy is?
Kinetic energy comes from movement. If the roller coaster is moving at the top of the hill, it has kinetic energy. if the rollercoaster isn't moving then it has potential energy.
Why it is difficult to drink liquid with straw on the top of the mountain?
It would be more difficult to drink with a straw on the top of a mountain because of low atmospheric pressure. You would not have as much pressure to push the drink up the straw.
What type of energy does a pebble sitting on the top of a mountain have?
It has potential energy.
How energy is harmful?
I can be harmful because sometimes when a large boulder is sitting on top of a small rocky hill and it starts to move which is called kinetic energy it might crush a person hiking below
Do a rock sitting on top of a cliff has no energy?
If it's not moving it doesn't have any energy
A rock sitting on top of a cliff has?
A rock that is sitting on top of a cliff has what is called potential energy.
What type of energy is A skier at the top of a mountain?
kinetic energy
Which of these is an example of potiential energy?
a rock sitting at the top of a hill
What type of energy does a builder sitting at the top of a cliff give off?
potential energy
What energy does a skierhas at topppof a hill and coming down a hill?
When skier is at the top of mountain he had kinetic energy which is further converted in to potential energy from the time when he start skiing from the top of the mountain.
What kind of energy does a balloon floating in the air have than a boulder a the top of a cliff?
what kind of energy does afloating balloon have
What type of energy does a boulder have as it sits on the top of a cliff 30 feet above the ground?
Gravitational potential energy as work is to be done to shift to such a height
What is the energy form of falling rocks from the top of a mountain?
Electrical Energy
Can you give me a good sentence for boulder?
The boulder teetered dangerously on the top of the hill.
