Motion
How fast an object is traveling over a given distance.
A) Acceleration
B) Speed
C) Distance
What is spee B) speed?
The less mass an object has, the less of this is needed to move it.
A) Force
B) Gravity
C) Resistance
What is A) force?
A force that that pulls objects to the center of the earth.
What is gravity?
An example of this force can be observed during a kickball game when the ball is pitched, but the force between the ball and the ground makes the ball stop before reaching the kicker.
What is friction?
A straight horizontal axis.
A) X-axis
B) Y-axis
C) Coordinate plane
What is the A) X-axis.
A change in speed.
A) Acceleration/deceleration
B) Distance
C) Time warp
What is A) acceleration/deceleration?
An object in motion will stay in motion, and an object at rest will stay at rest, unless acted upon by a(n) ____________ force.
A) Balanced
B) Unbalanced
What is B) unbalanced?
When two objects rub together, they create this force.
A) Static
B) Energy
C) Friction
What is C) friction?
The universal steps that scientist use to conduct experiments.
What is the Scientific Method

A) Time
B) Speed
C) Distance
What distance?
The best way to change the speed and number of cycles of our pendulum.
A) Adjust the beginning force
B) Adjust eh length of the string
C) Adjust the mass of the pendulum
What is B) adjust the length of the string?
What does F=MA stand for?
Force=Mass x Acceleration
A moving object will do this when friction is increased.
A) Speed up
B) Slow down
C) Nothing
What is B) slow down or stop?
When predicting the outcome of a race involving different sized cars down a ramp you must consider: mass, amount of force, distance, and this.
A) slope
B) temperature
C) timing
What is slope?
The X axis represents this on a line graph.
A) Distance
B) Speed
C) Time
What is C) time?
To find this use the formula distance/time (d divided by t)
A) Acceleration
B) Speed
C) Distance Traveled
What is B) speed?
If equal forces are balanced on an object, then this will happen with the object.
A) It will move
B) It will accelerate
C) No movement
What is C) NO movement?
This is the result when weight is added to a vehicle and the force is not increased.
What is slow down or reduce speed?
Two objects of different masses are dropped from the same altitude at the same time. They will hit the ground in this order.
What is at the same time?
When you have a straight line that is angled up it means this?
What is an object accelerating at a constant or steady speed?
In order to start something moving, this must be applied to the object.
A) Any force
B) A balanced force
C) An unbalanced force
What is an C) unbalanced force?
For every action, there is an _____________ and ___________ reaction.
What is equal and opposite
This is the energy of motion.
A) Potential Energy
B) Nuclear Energy
C) Kinetic Energy
What is C) kinetic energy?
An object has traveled 420 miles in 7 hours. This is the average rate of speed the object is traveling.
What is 60 miles per hour?
This describes the motion of an object's speed if the graph shows a horizontal straight line.
What is the object is the object is going at a steady speed.
