A ________ quantity is any quantity in physics that has BOTH MAGNITUDE and DIRECTION
Vector
friendly
scalar
angry
An object is in ____________if it changes position relative to a reference point.
standing still
motion
not moving
sleeping
Benjamin is running on a circular track. He maintains a constant speed but his velocity changes. This is because velocity depends on _________ as well as speed. So, even if Benjamin's speed remains constant, his velocity can change.
vibration
tone
measurement
direction
Evelyn is driving her car. She notices that her car's acceleration can result from a change in speed, a change in direction, or changes in ________.
both
velocity
speed
direction
The curved line on this distance-versus-time graph tells you that the object is ____________.
decelerating
stopping
accelerating
speeding
Nora is learning to drive. She manages to increase the car's speed from 0 m/s to 30 m/s in 10 seconds. What is the acceleration of the car?
Final speed = 30 m/s
Initial speed = 0 m/s
Time = 10 s
Remember (final speed – initial speed) ÷ time is acceleration.
10 m/s
10 m/s^2
3 m/s^2
30 m/s
Abigail, David, and Samuel are planning a trip to Cape Canaveral, Florida. They estimate that the journey will take them 10 hours. The distance from their home to Cape Canaveral is 816 km. Can you help them calculate the average speed they need to maintain for their trip? Use the formula s=d/t.
81.6 m/s^2
816 m/s
8.16 m/s
.816 m/s
Trinity, Kevin, and Savannah are participating in a race. During which two letters is Abigail moving at a constant speed?
a-b
b-c
c-d
d-e
Air resistance is also known as (a) and acts to slow objects down.
Air resistance is determined by air (a) on the surface area of the object 🡪 more surface area = more (b)
An automobile with an initial speed of 4.30 m/s accelerates uniformly at the rate of 3.0 m/s2. Find the final speed after 5.0 s.
a= Vf-Vi/t
In the absence of ____________, all objects dropped near the surface of a planet fall with the same constant acceleration
distance and time
pressure
terminal velocity
air resistance
Air resistance is a (a) force that opposes motion as the object moves through air
Jacorie drops a ball from the top of a building. The ball is considered a free falling object because it is falling under the sole influence of (a)
All objects free fall at the (a) rate of acceleration, regardless of their (b) .
An object falls from a high building. Ignoring air resistance, what will its velocity be after 6 seconds of falling?
Vf= Vi + at
What is the velocity of a motorcycle traveling 10 km West in 3 hours. V= d/t
.33 m/s
30 m/s
3.3 m/s
5 m/s^2
(a) is how far out of place the object is; it is the object’s overall
change in position.
As a roller-coaster car starts down a slope, its speed is 4 m/s. But 3 seconds later, at the bottom, its speed is 22 m/s. What is its average acceleration?
a=(Vf-Vi)/t
At which point does the object accelerate for a longer period of time. Click on the letter in the picture.
What is the formula to calculate velocity?
V = d/t
V = m/s
V = a/t
V = F/m
Which quantity in physics has both magnitude and direction?
Scalar
Vector
Speed
Acceleration
What does a horizontal line on a Velocity vs Time graph represent?
Constant velocity
Positive velocity
Negative velocity
Changing velocity
