100
How fast something is moving
What is speed
100

100
A push or a pull is known as a(n)
What is force.
100
The force that opposes the sliding motion two surfaces in contact.
What is Friction
100
The highest speed a falling object can reach.
What is Terminal Velocity.
200
Rate of change of position
What is Velocity
200
When object is speeding up, we call this __________ acceleration, and when it slows down ___________ acceleration.
What is Positive......and Negative
200
Exerting a force puts an object into ______.
What is motion.
200
Frictional force is based on what the material is made of and the __________ of that surface.
What is roughness/texture.
200
The force that opposes the motion of objects moving in the air.
What is Air Resistance.
300
Velocity is considered a vector because it has one of these
What is a direction
300
The calculation to find Acceleration.
What is Acceleration = (Final Velocity-Initial Velocity) / Time
300
The total amount of all forces acting on an object.
What is Net Force.
300
The frictional force that prevents two surfaces from sliding past each other. Example: Pushing a box across the floor.
What is static friction.
300
When a force is exerted on an object, the object does what?
What is move/change position.
400
What is the equation to calculate speed?
What is Speed = Distance/Time
400
An object is accelerating if it changes its speed or its _________.
What is direction.
400
When forces are of equal size and opposite direction, we that they are _______. This type results in zero motion.
What is balanced.
400
This type of friction resists the motion of an object that is already moving. Example: A baseball player stealing home under a tag.
What is Sliding Friction.
400
If Florence Griffith Joyner runs 100 meters and then turns around and runs 100 meters back to where she started, what is her total displacement?
What is 0 meters.
500
How fast something as moving at any particular instant or specific moment in time. This is what a car's speedometer displays.
What is Instantaneous Speed
500
On a Speed-Time graph, what part of the graph shows us the object's acceleration?
What is the slope of the line.
500
When forces are moving in opposite directions, an object will move in the direction of the ________ force.
What is strong/larger.
500
The type of friction that is the weakest and is associated with objects that are rolling.
What is Rolling Friction.
500
