Mrs. Decker is...
Our awesome science teacher.
200
A joule is...
A unit of work or energy.
200
The formula for force.
Mass times acceleration.
200
Speed is...
The time rate at which an object is moving along a path.
200
Sir Issac Newton was...
The creator of the Laws of Motion.
200
Friction is...
The resistance to motion of one object moving relative to another.
300
Give an example of an acceleration graph.
300
True or false: The net force is the sum of the forces acting on an object.
True.
300
True or false? Acceleration is time divided by velocity.
True.
300
Newton's 3rd Law of Motion
All actions need an equal and opposite reaction.
300
A force that is applied to an object by a person or object is called...
Applied Force.
400
Name one type of work and motion graph.
Constant speed graph, No speed graph, Velocity graph, Acceleration graph, constant velocity graph, constant acceleration graph.
400
Is this a balanced force?
Yes because there are 3 people on each side.
400
The formula for average speed.
Average speed= Total distance/Total time
400
Newton's First Law of Motion.
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
400
What is the total net force for an object if a man is pushing on one side with a force on 20N and if someone is also pushing it 45N?
Net force = 65N
500
Is a full speed graph a real graph? Yes or no.
No
500
Is this a balanced or unbalanced?
Unbalanced.
500
Average speed is distance divided...
Total elapsed time.
500
Newton's 2nd Law of Motion
The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.

A woman drives 20 miles in 1 hour and drives 40 miles in 2 hours. What is the average speed?
30 miles per hour.
