What energy does a pole-vaulter have?
It comes from the kinetic energy of the vaulter. As the horizontal motion stops, the pole then releases this stored elastic energy as it pushes the vaulter upward. So, in short the pole takes horizontal kinetic energy and stores it before using it to increase the gravitational potential energy of the vaulter.
What energy transformations take place in a race car during a race?
Race car drivers and teams monitor the engine for how effective it is transferring energy from potential and kinetic through RPM, or how fast the engine is moving. Kinetic energy inside the engine is transformed from chemical energy (fuel, air and spark plugs) to mechanical energy.
What two kinds of useful energy does a pole-vaulter need when making a jump?
The pole vault is a complex athletics event that requires considerable ability in sprinting, jumping, and gymnastics. The event is also characterized by substantial energy exchanges, particularly between the kinetic and gravitational potential energy of the athlete and the strain energy in the pole.
What force is used when pole-vaulter is in the air?
Between the first two instants, the only force acting on the pole-vaulter is the force of gravity.
How is energy transformed in a car?
When gasoline burns in a car engine, some of the chemical energy in the gasoline is converted into heat. The heat is converted into mechanical energy. The mechanical energy moves the car. Burning fuel in an electric power plant produces heat.
What type of energy increases as the pole bends before it propels a pole vaulter up into the air?
What energy increases as the pole bends before it propels a pole-vaulter up into the air? Elastic potential energy.
What energy transfer is taking place in a car engine?
You can see that a car engine transfers chemical energy , which is stored in the fuel, into kinetic energy in the engine and wheels.
What are the transformation of energy in driving a car?
When gasoline burns in a car engine, some of the chemical energy in the gasoline is converted into heat. The heat is converted into mechanical energy. The mechanical energy moves the car.
How does the pole impart its energy to the pole-vaulter?
The pole vault is all about energy conversion. The kinetic energy built up during the vaulter’s run turns into potential energy stored in the pole as the vaulter bends it nearly 90 degrees. When the pole recoils, it unleashes that energy to help propel the vaulter up and over the bar.
What do pole vaulters jump over?
Pole vaulting, also known as pole jumping, is a track and field event in which an athlete uses a long and flexible pole, usually made from fiberglass or carbon fiber, as an aid to jump over a bar.
How is pole vaulting done?
Pole-vaulting is conducted along the lines of the high jump; i.e., vaulters attempt to vault over a crossbar… A slideway, or box, is sunk into the ground with its back placed directly below the crossbar (see illustration). The vaulter thrusts the pole into this box upon leaving the ground.
What kind of energy makes a car move?
A moving car possesses mechanical energy due to its motion (kinetic energy).
