Describing Motion
Acceleration
The Nature of Force
Friction & Gravity
Newton's Laws
100
This is the SI unit for length
What are meters
100
This is the unit for acceleration
What is meters per second squared
100
This is the SI unit for force
What is the Newton
100
This acts in the opposite direction as force
What is friction
100
This law states that for every action there is an equal and opposite reaction
What is Newton's third law
200
This is the formula for speed
distance divided by time
200
These are three examples that define acceleration
What is increasing speed, decreasing speed, and changing direction?
200
When two forces are acting in equal and opposite directions, we call it this
What are balanced forces
200
He is the most "attractive" person in the room due to his large mass
Who is Mr. Arnold
200
This law states that an object at rest will remain at rest unless acted upon by an outside force
What is Newton's first law
300
When you divide rise by run you are calculating this
What is slope
300
To find an objects acceleration, you need to know its starting speed, its ending speed and this
What is time
300
This occurs when the net forces acting on an object are unbalanced
What is motion
300
These two words are what we call the force acting on fish as they swim through the ocean.
What is fluid friction
300
This is defined as the tendency of an object to resist a change in motion
What is inertia
400
This is the difference between speed and velocity
What is direction
400
A flat line on a distance-versus-time graph would show that an object is doing this
What is not moving
400
Weight is how we measure this force
What is gravity
400
These are the two factors that affect the amount of gravitational attraction between two objects
What is mass and distance
400
This is the formula for determining accelration
What is net force divided by mass
500
This is a place or object used for comparison to determine if something is in motion.
What is a reference point
500
This is the rate at which objects accelerate in a vaccum
What is 9.8 meters per second squared
500
Like velocity and acceleration, a force is described by its strength and this
What is direction
500
This law states that the force of gravity acts between all objects in the universe
What is the law of universal gravitation
500
The momentum of an object can be calculated by multiplying these
What is mass and velocity
M
e
n
