Graphs
Meters per second (m/s) are units of what?
Speed
a force requiring touch
Contact Force
hypothesis
Energy cannot be created or destroyed
Law of Conservation of Energy
Gravitational force
What can you interpret from a motion graph?
Speed, distance, time, if they're stationary
During a tug of war game the rope is not moving. What is this an example of?
Balanced forces
The variable you change during an experiment
Independent variable
Stored energy; depends on an objects height and mass
Potential energy
A force that is opposite in direction and not equal in size; results in change of motion
Unbalanced Force
How do you calculate speed?
Distance / Time
Between charged objects; non-contact force; hair sticking to a balloon
Electrical force
You conduct multiple trials within an experiment
Repetition
Energy due to motion
Kinetic energy
a force that can act on an object without physically touching it
Non-contact force
Draw a graph where the person is staying stationary.
(any graph with horizontal line)
overall force on an object when all individual forces on it are added together
Net force
The variable you are measuring during an experiment; the result
Dependent variable
Sum of kinetic energy and potential energy; energy of motion
Mechanical energy
unit of force
Newton (N)
What does a curved line show on a distance vs time graph?
A change in speed.
the force that two surfaces exert on each other when they rub against each other
Friction
A different scientist preforms another scientist's experiment
Replication
Negative acceleration
north and south poles interact
Magnetic force
