Energy
The energy an object has due to its motion.
What is Kinetic Energy
A force of attraction between two masses.
What is Gravity.
How much ground has been converted during the movement of an object.
What is Distance.
When an object pushes on another object, the object being acted upon pushes back with equal force.
What is Newton's Third Law.
The stored energy an object has because of its position or state.
What is Potential Energy.
When a force acts upon an object to cause it to move.
What is work.
The resistance to motion when two objects rub against one another.
What is friction.
An object in motion stays in motion; an object at rest stays at rest until acted upon by an external force; (inertia).
What is Newton's First Law.
The amount of energy doesn't change; energy is not created or destroyed; it is only converted to other forms of energy.
What is the Law of Conservation of Energy.
A push or pull that causes an object to have a change in movement or direction.
What is Force.
The rate at which an object travels in a certain amount of time.
What is Speed.
The measurement of how much matter is in an object; objects with greater ---- feel heavier, and objects with less ---- feel lighter, regardless of size.
What is Mass.
The speed and direction of an object.
What is Velocity.
A mechanical device with few or no moving parts that is used to simplify the motion of an object and reduce the needed force.
What is a Simple Machine.
The speed of an object at a specific instant in time.
What is Instantaneous Speed.
The greater the mass of an object, the greater force needed to accelerate the object. (Force= Mass x Acceleration).
What is Newton's Second Law.
Any change in direction and/or speed, either faster or slower.
What is Acceleration.
A mechanical device made of two or more simple machines.
What is a Complex Machine.
The change in position of an object.
What is Motion.
