4PS3-1 vocab
the distance an object moves in an amount of time
speed
a force that results from the interaction of two objects in contact with each other
contact force
How are energy and speed related?
what is the relationship between energy and mass?
the more mass something has, the slower it goes, which means the less energy it has
the energy that is stored inside of an object
potential energy
force that occurs without objects touching
non-contact force
which do you think will roll faster.. a marble rolling down a ramp at low height or a marble rolling down a ramp at a higher height?
a marble rolling down a ramp from a higher height
what happens when objects collide?
energy transfers
the energy an object has because it is moving
kinetic energy
a non-contact force that acts over a distance and pulls all objects towards each other
gravity
when does the marble have more energy.. going down a ramp from a higher height or a lower height?
the marble has more energy going down a ramp from a higher height
what does transforming energy mean?
changing energy from one type to another
the speed and direction of an object
the movement of energy from one object to another or the change of energy from one form to another
transfer of energy
describe how velocity is different from speed
velocity includes the direction of an object, speed does not
what does transferring energy mean?
moving energy from one object to another
acceleration
the theory that states that energy may change form, but it cannot be created or destroyed
conservation of energy (Newtons Law)
what is force?
force is any push or pull
in a car crash, what happens to the kinetic energy of the car when it collides?
the kinetic energy is transformed to other types of energy: for example, sound energy and heat energy
