What is the formula for speed?
s = d / t
100
What is energy?
The ability to cause changes in matter.
100
What is motion?
When the distance from another object is changing
100
On a distance vs. time graph what does a straight line represent?
No motion
100
Will flow of electrons stop if the circuit is open?
yes
200
What is the formula for average speed?
as = td / tt
200
What is potential energy?
The energy an object has because of its position or condition (stored)
200
What is speed?
the measure of how quickly an object gets from one place to another
200
What is on the y-axis on a distance vs. time graph?
distance
200
What is voltage?
a force that pushes the current through the circuit
300
What is the formula for acceleration?
final speed - initial speed / time
300
What is thermal energy?
Kinetic energy of the particles that make up a substance (heat)
300
What is inertia?
when an object resists a change in motion.
300
What is slope on a graph?
the steepness of a line
300
What is a series circuit?
When there is only one path for electrons to go thorugh
400
What is velocity determined by?
speed and direction of an object
400
What type of energy can travel through space?
Light energy
400
What is acceleration? (all 3 things)
increase in speed, decrease in speed, or change in direction.
400
What way will a line be if it is in motion?
Vertical
400
What does a wire have to be touching in order for alight bulb to light when using a battery?
A conductor
500
The car started off sitting still at 0 m/s. After 10 seconds it was at 40 m/s. What is the difference of acceleration?
40 m/s - 0 m/s / 10s = 4m/s2
500
What does sound energy travel in?
Waves in vibrating matter
500
How can you describe motion?
a reference direction such as North, South, East, or West
500
If a line is getting straighter and the object is slowing down on a distance vs. time graph what is happening.
Negative acceleration
500
What are electromagnetic waves?
waves which can travel through the vacuum of outer space.
