A girl moves on her bike 47 m [E] in 24 seconds. What is her velocity?
The symbol v1 is.....
acceleration due to velocity
initial velocity
gravitational velocity
final velocity
The unit for acceleration is....
m/s
s2
m2/s
m/s2
speed is not a vector because it doesn't have ....
a value
a square
a direction
a velocity
Δt means...
total time
negative time
start time
change of time
The acceleration due to gravity on Earth is a constant. Its value is...
12.1 m/s2
9.8 m/s2
8.6 m/s2
5.9 m/s2
Which equation would you use if the acceleration is unknown?
v2 = v1 + aΔt
Δd = 1/2(v2 + v1)Δt
Δd = v1Δt + 1/2aΔt2
v22 = v12 + 2aΔd
Which equation would you use if the time is unknown?
v22 = v12 + 2aΔd
Δd = 1/2(v2 + v1)Δt
Δd = v1Δt + 1/2aΔt2
v2 = v1 + aΔt
Which one is an example of speed?
Usain Bolt ran 100 meters in 9.8 seconds
The plane flew 100 km [SW] in 1 hour
A horse starts a race at rest and accelerates [N] at 2.0 m/s2 . What is the horse's velocity after 6 seconds?
On the moon, an astronaut drops a feather and a hammer from the same height. If they were dropped at the same time, which one hits the ground first?
same time
feather
hammer
they both don't drop
check all the values that are vectors (more than 1)
