100
How fast an object is traveling over a given distance.
What is speed?
100
The less mass an object has, the less of this is needed to move it.
What is force?
100
A force that that pulls objects to the center of the earth.
What is gravity?
100
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?
100
On a graph, what axis represents time
What is the x-axis.
200
A change in speed.
What is acceleration/deceleration?
200
An object in motion will stay in motion, and an object at rest will stay at rest, unless acted upon by an ____________ force.
What is unbalanced?
200
When two objects rub together, they create this force.
What is friction?
200
Three friends, Mary, Sue, and Thomas enter a race. Mary finishes in 10.08 seconds. Sue finishes in 10.081 seconds, and Thomas finishes in 10.080 seconds. Who came in last?
What is Sue?
200
On a graph, what axis represents time.
What is the x-axis?
300
Bob threw a ball into the air. What force caused the ball to change direction and fall back towards his hand?
What is gravity.
300
If a skier travels 10 meters in one second, 20 meters in the next second, and 30 meters the third second. What can be inferred?
What is the skier is speeding up or accelerating.
300
A moving object will do this when friction is increased.
What is slow down or stop?
300
A delivery truck traveled 150 miles in 3 hours. What was its speed?
What is 50 mph?
300
How long was the car stopped?
What is 5 seconds.
400
To find this use the formula distance/time (d divided by t)
What is speed?
400
If equal forces are balanced on an object, then this will happen with the object.
What is NO movement?
400
This is the result when weight is added to a vehicle and the force is not increased.
What is slow down or reduce speed?
400
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?
400
How far from home was the car at 9:30?
What is 60 miles away.
500
In order to start something moving, this must be applied to the object.
What is an unbalanced force?
500
If a golf ball and a bowling ball are dropped from the same height, at the same time, which will hit the ground first?
What is they will hit at the same time. Weight or mass does NOT affect the speed at which objects fall.
500
What is the relationship between mass and acceleration?
What is the greater the mass, the greater the force needed to accelerate the object.
500
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?
500
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.
