Worksheet time: 40mins
Which car is accelerating?
a car that is unmoving
a car that rounds a curve at a constant speed
a car that travels in straight line at a constant speed
a car that is set to a constant speed of 60 miles per hour
What is the velocity in meters per second of a runner who runs exactly 110 m toward the beach in 63 seconds.
0.654 m/s toward the beach
1.74 m/s toward the beach
15.3 m/s toward the beach
7920 m/s toward the beach
Find the average speed of a horse that traveled East for 27 km in 4 hours.
6.75 km/h due East
67.5 km/h due East
67.5 km/h
6.75 km/h
In which situation is the acceleration of the car negative?
The velocity of a car was 45 km/h at 2:00 pm and at 4:00 pm the velocity of the car was 85 km/h.
The velocity of a car increased from 40 km/h to 75 km/h over 15 minutes.
The velocity of a car reduced from 60 km/h to 25 km/h over one minute.
The velocity of a car was 75 km/h over 4 hours.
Diego kicks a soccer ball from the end line. His fellow students time and mark the soccer ball as it moves down the field. The graph represents the ball's progress.
Based on the graph, during what time is the velocity constant and positive?
from 0 to 1.5 seconds
from 3.0 to 4.5 seconds
from 4.0 to 5.0 seconds
from 2.5 to 3.5 seconds
Zury travels from her house to her mom's office building. From there, she walks to school. After school, she walks to the library and then to a friend's house before finally ending back at home. Find Zury's total displacement.
3.15 miles W
1 mile N
0.4 miles E
0 miles
Which object is accelerating?
A water bottle standing motionless on a desk.
A whistle on a string whirled in a circle at a constant speed.
A car driving straight along a a highway at a constant speed.
A helicopter hovering perfectly still over a rescue mission.
Erik has been driving 65 mph for the last half hour. The truck next to him has been there for a while now, so Erik is correct to assume that the
truck is parked.
speed of the truck is 70 mph.
speed of the truck is 65 mph.
speed of the truck is 60 mph.
Which graph illustrates constant speed?
(Notice it's a SPEED time graph)
A
B
C
D
Sally and Sue took a canoe trip down the Mississippi River. Their average speed for the trip south was 18 miles/hour. 18 miles/hour south is the girls'
velocity
distance
speed
acceleration
A pilot on a plane watches a goose that has been flying alongside the plane for a few minutes. Which pair of objects most closely resembles the frame of reference described above?
a car driving towards a stopped car
a car driving past a slow moving train.
two Olympic sprinters standing ready at the starting line
a train driving straight towards another train on the track next to it
In which situation are both the speed and velocity of the bicyclist changing?
The bike turns left at 5 m/s.
The bicyclist travels down a straight track at 15 m/s.
The bike travels around a circular track at 15 m/s.
A bicyclist traveling at 15 m/s slows to 10 m/s and turns the corner.
A car is moving at a speed of 24.0 m/s . The driver brakes so that the car decelerates at 3.4 m/s2 .
What is the instantaneous final velocity of the car 4 seconds after the driver brakes?
Remember: fv = iv + ( a x t )
10.4 m/s
37.6 m/s
5.15 m/s
21.2 m/s
Cars A, B, C, D and E are moving on tracks from left to right. The lengths of the tracks are the same. Assuming each car started at the beginning of its track, which cars are moving at a constant velocity?
B and D
C and E
A and C
D and A
Which BEST compares the motions of dots C and D?
Both C and D are speeding up.
Both C and D are moving at a constant velocity.
C is speeding up and D is moving at a constant velocity.
C is slowing down and D is moving at a constant velocity.
The difference between speed and velocity is that
speed is a vector and requires a direction.
velocity is a vector and requires a direction.
speed is a vector and requires a magnitude.
velocity is a vector and requires a magnitude.
Both speed and velocity measure how fast something is moving. However, since speed is not a _________ it does not require a(n) ___________
quantity, unit
magnitude, unit
scalar, direction
vector, direction
Ziya walks 15 meters forward and then 5 meters backwards. Which statement most accurate describes the magnitude of her displacement and distance travelled?
Ziya's displacement is 5m less than her distance travelled.
Ziya's displacement is 10m less than her distance travelled.
Ziya's displacement is 5m greater than her distance travelled.
Ziya's displacement is 10m greater than her distance travelled.
