Kinematics is the study of
forces
motion
acceleration
energy
The scalar form of velocity is
distance
speed
acceleration
time
Velocity is ...
speed with direction
speed with time
speed with distance
speed with acceleration
The scalar form of displacement is
distance
speed
acceleration
time
Which one is missing final speed?
d = v0 t + ½ a t2
v = v0 + a t
v2 = v02 + 2 a d
(v + v0) / 2 = d / t
Which one is missing time?
d = v0 t + ½ a t2
v = v0 + a t
v2 = v02 + 2 a d
(v + v0) / 2 = d / t
Which one would you not use to find flight time?
d = v0 t + ½ a t2
v = v0 + a t
v2 = v02 + 2 a d
(v + v0) / 2 = d / t
Which one is missing distance?
d = v0 t + ½ a t2
v = v0 + a t
v2 = v02 + 2 a d
(v + v0) / 2 = d / t
In free-fall, the only force considered is
friction
force due to gravity
air resistance
applied force
True or false?
If you throw a ball up in the air, it is in free-fall immediately after it leaves your hand.
True
False
At the top of its path, the vertical component of the velocity of a projectile
is constant
is zero
is about 10 m/s2 down
depends on the initial velocity
You throw a ball up into the air and then catch it at the same height. Compared to the speed with which you threw it, the ball will be moving
faster
the same speed
slower
A heavy ball and a light ball are dropped from the same height from rest at the same time.
Which one will hit the ground first?
the heavy ball
both will hit at the same time
the light ball
More information is needed.
When you drop a ball from rest it accelerates downward at 9.8 m/s2.
If you instead throw it downward, assuming no air resistance, its acceleration immediately after leaving your hand is
more than
9.8 m/s2.
9.8 m/s2.
less than
9.8 m/s2.
Cannot say, unless the speed of thrown is given.
True or false?
Acceleration can be measured in m/s.
True
False
True or false?
When Mr. Nodler rides his tricycle at a constant speed in a circle, he must be accelerating.
True
False
True or false?
An object is released from rest. It will fall 10 m during the first second.
True
False
True or false?
Speed is a vector quantity, and velocity is a scalar quantity.
True
False
True or false?
If a light ball and a heavy ball are dropped from rest from the same height at the same time, the heavier ball will reach the ground first.
True
False
