an explanation of why things
happen that is tested, but is constantly undergoing change; a synthesis
of a large body of information that encompasses well-tested and verified
hypotheses; not set and can undergo change
When colliding objects become entangled or coupled together, thereby generating heat or disfigurement
- Energy is lost during the collision (usually due to heat or friction); there is a change in shape
List Newton's three laws of motion in YOUR OWN WORDS and gives examples of each.
1. inertia, an object that moves will keep moving, and object at rest will not move, unless another force acts on it
- a ball rolling across a frozen pond, it dose not slow down
2. F=ma, acceleration and mass are directly proportional to force
3. for every action there is an equal opposite reaction
If a rock in a sling-shot has 700
J of potential energy, what type of potential energy is it? How much
kinetic energy will the sling-shot have after it is fired without air
resistance? With air resistance?
If you are in space
(frictionless) and you throw an object that is less massive than you,
which will move away faster, you or the object? What if the object is
more massive than you? What if the object is the same mass as you?
