Define Motion
The position of an object, that changes relative to another object
A push or pull is a….
Force
The amount of work done when both movement and the force are in the same direction is…
Maximum
What is the rate at which work is done, and equals the amount of work done on an object in a unit of time?
Power
Mrs. Nicosia lifts a plant 3 meters with the force of 60N. How much work does she do?
180 joules
60 × 3 = 180
If you carry a box 3 meters in 20 seconds, with the force of 100N. How much power is used?
15 joules
100N x 3 meters= 300 300/20= 15
How many watts (units of power) does a light bulb transfer 80 joules of energy in four seconds?
20
80/4= 20
____ is energy in motion, that depends on speed and mass.
Kinetic Energy
____ is energy not in motion, that is stored.
Potential Energy
_______ is energy dependent on the objects compression and stretch.
Elastic Potential Energy
________ is energy related to an objects vertical position and depends on how high an object is off the ground.
Gravitational Potential Energy
Give an example of Gravitational Potential Energy
An apple hanging at the top of a tree.
Give an example of Elastic Potential Energy
A bow being stretched back to fit an arrow.
_______ is the energy an object has due to its motion, shape, position, or combination of these factors.
Mechanical Energy
Nuclear energy is the type of potential energy that is tired in the…..?
Nucleus
If there is an increase in thermal energy and particle motion increases, then what type of energy is the greatest?
Kinetic Energy
If batteries operate due to chemical reactions, then what energy is stored within?
Chemical Energy
Describe the law of conservation of energy.
When one object loses energy, other objects must gain it. Energy moves from one place to another or changes from but none is created or destroyed.
______ is when energy changes from one form to another.
Energy Transformation
