Forces
What is a force?
A push or pull
This is stored Energy
Potential energy
What is a dependent variable?
The variable that is being measured or tested in an experiment
These are forces that are equal in size but opposite direction
Balanced Forces
Sand is sometimes spread on an icy surface in order to_______________
Increase friction
This is the force of attraction between all objects in the universe
Gravity
This is energy of motion
Kinetic
a variable that stands on its own. It is the variable that the experimenter manipulates or changes
This is the measure of the pull of gravity on a sample of matter
weight
This is the action or process of moving or being moved
Motion
This is the force that opposes motion
Friction
List 3 renewable sources of energy
solar, wind and water
The values that do not change either during or between experiments
What two factors determine the gravitational attraction between objects in the universe?
Mass and distance
What is the formula for Average Speed
Average Speed = Distance traveled divided by Time
These are materials that reduce friction
lubricants
What is the law of conservation of energy
energy cannot be created nor destroyed, but only change form
List 2 lab safety rules
tie your hair back, wear goggles, etc.
What keeps planets and satellites in orbit?
Gravity
This is the quantity of motion of a moving body, measured as a product of its mass and velocity.
Momentum
List 3 lubricants
oil, grease, wax, lotion
What is the speed of something in a given direction.
Velocity
This is the series of steps to guide you when answering or solving problems
Scientific Method
What is an instrument used to measure weight
Spring Scale
This is the force that is needed to keep a surface sliding along another surface.
Sliding Friction
