Fig Newtons
What is Newton's second law of motion?
F=ma
An object at rest has what type of energy?
Potential energy
The variable found on the x-axis of distance vs time graphs.
What is time?
Negatively charged subatomic particles.
What are electrons?
The manipulated/changed variable.
Independent Variable
In an ideal world, a ball dropped from 100cm will bounce how high according to Newton's third law of motion?
100cm
An object in motion has which type of energy?
Kinetic energy
A flat line on a distance vs time graph represents this.
What is no motion/movement?
An area in space where a force is created without physical contact.
What are fields?
A testable and falsifiable statement made before an experiment.
What is a hypothesis?
In order to move an object, what must act on the object?
What is an unbalanced force?
The point where a pendulum has the greatest amount of potential energy.
What is the top of the swing.
Draw a line that represents an object returning to the origin on a distance vs time graph.
Negative slope
The subatomic particles found in the nucleus of an atom.
What are protons and neutrons?
A graphical analysis which shows how the dependent variable changes over a time period.
What is a line graph?
What amount of force is needed in order to accelerate a 2kg object at 15m/s?
30 N
The point in a fall at which the PE and KE are equal.
Half way
What is represented by the line on a distance vs time graph.
What is velocity?
Name one group from the periodic table.
Reactive metals, transition metals, metals, radioactive, metalloids, non-metals, halogens, noble gases.
Researchers dropped a 10 gram mass on a pendulum from 120, 140, and 160 degrees. The mass contacted a weighted block and the distance the block traveled was measured. What are the experimental variables?
IV = Angle
DV = Black distance
CV = Same mass/block
What is the mass of an object that has been accelerated at 15m/s by a force of 30 newtons?
2kg
The law which states that the total energy in a system is always the same/constant.
The law of conservation of energy.
How a person can calculate the velocity/slope of a line on a distance vs time graph.
What is rise over run?
This is what is counted for each period on the periodic table.
Number of orbitals.
What must be included in experimental design ensure the experiment is more reliable.
