What is a force?
A push or a pull
100
This is a measure of how fast something moves through a distance in a given amount of time.
What is speed?
100
What unit is used to measure speed?
m/s
100
What unit is used to measure acceleration?
m/s2
100
What is the unit for force?
Newtons (N)
200
What is Newton's First Law of motion?
An object at rest remains at rest & an object in motion will remain in motion unless there is an unbalanced force acting on the object.
200
What is Newton's Second Law of motion?
Objects with larger mass require more force for motion and objects with a smaller mass require less force for motion
200
What formula would you used to solve for force?
mass x acceleration
200
What is Newton's Third Law of Motion?
the Law of Motion that states for every action there is an equal and opposite reaction
200
What happens if there is no force acting upon an object?
It will continue to move at the same speed in the same direction.
300
What would happen if you threw a ball in the air in outer space?
It will travel in a straight line forever
300
If an object is Balanced, the Net Force would only be equal to?
0 N
300
A rock is at rest on the sidewalk. What type of force is acting on the rock AND what is the net force?
A balanced force
Net force= 0N
300
If we are calculating net force of an object and we have two opposing forces we need to ___________ the forces to get net force
Subtract
300
What is the motion of the object in the graph from 0 - 6 minutes?
It is moving at a constant rate.
400
To solve for acceleration what two things do you need to know?
The objects force and mass
400
What is the motion of the object in the graph from 12-18 minutes?
The object has no motion, it is at rest.
400
A change in a moving object's speed or direction is..
What is Acceleration?
400
When graphing a car's speed, what is the independent and dependent variable?
Independent = time
Dependent = speed
400
When given a Position vs. Time graph, the motion on the object is the same as a....
Distance vs. Time Graph
500
What is the relationship between speed and kinetic energy?
The greater the speed of an object the greater it's kinetic energy.
500
How do you find the average speed?
total distance/total time
500
This acts to oppose/resist change in motion....
Inertia
500
A combined force that causes something to move...
An Unbalanced Force
500
What slows down the motion of an object or keeps it from starting?
Friction
