Speed & Kinetic Energy
This is the energy an object has just because it is moving.
Kinetic Energy.
When a moving object hits a still object, energy moves from one to the other. This process is called this.
transferred (or transfer).
A stove converts electric energy into this form to cook food.
Heat Energy.
This heat transfer method works through touching, like when a hot stove heats a pot.
A. radiation
B. conduction
C. sound energy
conduction
If a ball is going fast and the same ball is going slow, the fast ball has more of this.
KINETIC ENERGY
What happens to the energy of a fast baseball when it hits a bottle and breaks it?
The small object moves with great speed.
What energy change happens when a solar calculator uses the sun to work?
Light → Electric.
Energy travels from the Sun to Earth through space using this method..
A. conduction
B. radiation
C. electrical
Radiation
To make an object's energy of motion bigger, you must increase its speed or its weight.
its weight
Two types of energy that are often made when two objects crash and make noise and get warm.
Sound and Heat (Thermal) Energy.
When you turn on a toy car, the battery's stored energy changes into this energy to make the wheels SPIN.
Motion (Kinetic) Energy.
This type of energy is being transferred when you hear a loud guitar that is far away.
A. conduction
B. electrical
C. sound
Sound energy
A skateboarder must do this action to increase the kinetic energy they need to go faster up a ramp.
Pump their legs harder.
This happens to the SPEED of a baseball bat immediately after it hits the ball.
It slows down (or decreases its speed).
A light bulb takes in electric energy and gives out these two main energy forms.
Light and Heat (Thermal) Energy.
When you plug in a fan, this energy moves from the wall to the fan's motor.
A. radiation
B. convection
C. electric current
Electric Current.
If a heavy rock and a light feather travel at the same speed, this object has more energy.
The answer is the heavy rock (or the ball with more mass).
When a moving car hits a parked car, the parked car starts to move. This proves that the moving
The answer is motion energy was transferred.
What is the final form of energy that comes out of a microphone plugged into a speaker?
sound Energy.
The heat transfer method where warm air rises and cool air sinks, like steam above a boiling pot.
A. radiation
B. convection
C. electric current
Convection
