Name two possible types of energy absorbing materials which could be used to protect your egg.
foam, balloons, bubble wrap, rubber bands, styrofoam,
a push or a pull that causes an object to change its motion (that is, start moving, stop moving, or change direction)
force
the ability to cause change in a system or cause movement
energy
At the top of the ramp the marble had _____ potential energy.
gravitational
When your mousetrap is released, elastic potential energy is released as _______ energy.
Kinetic
When the balloon is inflated it has ________ potential energy, and when it begins to deflate it has _______energy
elastic, kinetic
When the crash test car hits the wall at the end of the ramp, all of its kinetic energy will have been converted into ______, causing the front end to crumple..
work
the rate at which the velocity of an object changes over time
acceleration
the energy associated with the movement of objects
kinetic energy
Which way was the friction force pushing against the marble as it rolled down the track
opposite of the motion of the marble
Which spring has more elastic potential energy, a mousetrap spring or a rat trap spring?
Rat trap spring
How can we increase the distance the balloon car moves?
We can decrease the mass of the car or increase the amount of air in the balloon.
Which type of wheel will produce the most amount of thermal energy from friction? (drag wheel, cd wheel)
drag wheel
the energy stored in an object because of its position in a gravitational field, usually as a result of being elevated above the ground.
gravitational potential energy
matter through which a wave travels, such as a solid, liquid, or gas
medium
By time the marble has fallen into the pool and stopped moving, all of the kinetic energy will have been converted into _________ energy.
thermal
What is done when a force is applied to move the mousetrap arm back?
Work
How can we increase the kinetic energy of a balloon?
Increase the mass of gases in the balloon
By the time the crash car goes all the way done the ramp, all of its gravitational potential energy will have been converted to what three kinds of energy.
sound, thermal, kinetic
the energy stored within the chemical bonds of a substance due to the structural arrangement of its atoms or molecules
chemical potential energy
a form of mechanical kinetic and potential energy created when a force causes an object to vibrate, sending longitudinal (pressure) waves through a physical medium such as a solid, liquid, or gas.
sound energy
What are three types of energy created from gravitational potential energy as the marble begins to move down the ramp?
Kinetic energy, sound energy, thermal energy
The amount of work done to pull the mousetrap arm back completely is (greater than, less than or equal to) the energy stored by the spring.
equal to
Force is used to push air into the balloon, how much force does the balloon push back with and which way does the car move? Which law of motion predicts this?
The balloon pushs air out with an equal and opposite force. Newton's third law
The amount of work required to push the crash test car up the ramp is (greater than, less than, or equal to) the amount of gravitational potential energy stored in the car.
equal to
the mechanical energy stored inside an object when it is temporarily stretched, compressed, twisted, or deformed by an outside force. [1, 2]
elastic potential energy
the total energy of an isolated system remains constant over time. Energy cannot be created or destroyed; it can only change forms or be transferred from one object to another.
law of conservation of energy
What are two ways we can increase the gravitational potential energy of the marble?
Increase the height of the ramp, increase the angle of the slope, use a larger marble.
