Energy
What is energy?
The ability of a system to do work
What is force?
A push or pull that can change the motion of an object
What is motion?
The change in an object’s position with respect to time and in comparison with the position of other objects used as reference points
What is a line graph?
A graph in which the data are represented by points connected by one or more lines
What is Newton's 1st Law
an object will not change its motion unless a force acts on it
What are the two energies within a system?
potential and kinetic energy
What kind of force causes an object motion?
an unbalanced force
What kind of graph best represents motion?
Line Graph
What is an x and y axis?
An x axis is the independent variable and the y axis is the dependent variable
What is Newton's 2nd Law?
the force on an object is equal to its mass times its acceleration
f= m x a
Define potential and kinetic energy
potential energy is stored energy and kinetic energy is energy being used
If there are two areas evenly pushing against an object will this cause the box to move? What kind of force is this?
No, its a balanced force
What is the formula for speed?
S= d/t
Which axis is time on and why?
X axis, its an independent variable
What is Newton's 3rd law?
states that for every action (force) in nature there is an equal and opposite reaction.
What is the unit of measurement for energy?
Joules
What is the unit of measurement of force?
Newtons (N)
Define speed
The rate of change of position (or distance traveled) with respect to time
What can be found on the Y axis?
Distance, position, and speed
When an object starts moving does it have any potential energy?
Yes, it will decreases as it moves
Give an example of kinetic energy transferring from one object to another.
bowling ball hitting pins, knocking dominoes over, pool balls colliding
What is the formula for force?
f= m x a
a constant speed
Which type of graph can never have a line decreasing?
What is the law of conservation of energy?
The total change of energy in any system is equal to the total energy transferred into and out of the system.
