An ambulance was invented that could travel at the same speed as a helicopter. If an ambulance left Vidaliia at the exact same moment as the helicopter, which one would reach Savannah first, and why?
The helicopter would reach Savannah first because it only had to travel the displacement velocity.
The helicopter would reach Savannah faster, because the helicopter is capable of traveling faster than an ambulance.
The ambulance would get there faster than the helicopter because it has a siren and could travel full speed through any intersection.
The ambulance would get there faster because it does not have as many people traveling in it.
What is the speed of a runner who runs 400 meters in 40 seconds?
10 meters/second
40 meters/second
100 meters/second
1,600 meters/second
An unbalanced force is when objects move in one direction because the force is greater from that direction.
true
false
An automobile you are riding in suddenly stops, why does your body continue to go forward?
An object in motion stays in motion.
Gravity pulls your body towards the earth.
Friction makes your body slow down.
If you push a tennis ball, a bowling ball, and a basketball with the same amount of force, which one will go farthest?
bowling ball
tennis ball
basketball
If a magician pulls a table cloth from under a table of dishes, what should happen based on Newton's 1st law?
The dishes will stay in place on the table.
The dishes will fall to the ground.
The dishes will accelerate and then slow down.
It is much more difficult to move a dresser full of clothes than an empty dresser. Why?
An object in motion stays in motion.
It takes more force to move an object with more mass.
It takes more friction to move the empty dresser.

What is our most common frame of reference?
the sun
the moon
the Earth

What is acceleration?
The change in position over time.
The change in velocity over time.
Speeding up
Slowing down
If an object has a positive velocity and a positive acceleration it is...
Speeding up
Slowing down
Changing direction
Stopping
If an object has a positive velocity and a negative acceleration it is...
Speeding up
Slowing down
Changing direction
Stopping
Velocity is different from speed because...
Velocity is distance/time. Speed is displacement/time.
Velocity is speed in a certain direction and can be positive or negative.
Speed is velocity in a certain direction. Both can only be positive.
Velocity is how much speed changes over time.
Which of the following is NOT an example of acceleration?
Driving at a steady speed and turning left.
Driving at a steady speed and then slowing down.
A change in velocity from 40km/h to 65 km/h
A car moving at a steady speed of 60 km/hr.
What is motion?
the location of an object
the change in position over time
distance divided by time
the velocity of an object
What is acceleration?
A change in position over time.
The rate at which one quantity distance changes compared to another quantity time
The rate at which velocity changes
A measure of how far something moves in a given amount of time.
If a truck travels at a steady velocity, will there be any acceleration?
Yes
No
Speed in a specific direction is called
velocity
