Station 1: Speed, Velocity, & Acceleration
Station 2: Newton’s Laws
1. Sort each card as a demonstration of Speed, Velocity, or
Acceleration.
2. Answer the questions:
1. Newton’s Laws Scenarios- determine which law relates to each
scenario, sort into the Venn diagram.
2. Answer the questions:
Velocity
Speed
Acceleration
Several students created a chart to describe speed velocity and
acceleration.
Student A
Acceleration is
the distance
traveled divided
by the time it
took to travel the
distance.
Student B
Student C
Student D
Acceleration is
the change of
velocity in a
certain amount
of time.
Acceleration is
the change of
velocity in a
certain amount
of time.
Acceleration is
only when an
object changes
direction
Speed is the
change of
velocity in a
certain amount
of time.
Speed is the
distance
traveled divided
by the time it
took to travel the
distance.
Velocity includes
direction and is
the
displacement of
an object
divided by the
time it took to
travel the
distance.
Velocity includes
direction and is
the
displacement of
an object
divided by the
time it took to
travel the
distance.
Speed includes
direction and is
the
displacement of
an object
divided by the
time it took to
travel the
distance.
Speed is the
distance

Velocity is the
distance
traveled divided
by the time it
took to travel the
distance.
Velocity includes
direction and is
the
displacement of
an object
divided by the
time it took to
travel the
distance.
Which student’s description is most accurate?
a.
b.
c.
d.
Student A
Student B
Student C
Student D
Displacement of an
object refers to direction.
Speed- distance & time
Velocity- speed & direction
Acceleration- speeding up, slowing down, changing
directions
The car a person is riding in stops suddenly. The person is not wearing
a seatbelt. Newton’s Laws state that the person’s body will –
a.
b.
c.
d.
stop with the car
continue to move straight ahead
move suddenly backward
move to one side
Newton’s 1st- An object in
motion will stay in motion
unless an unbalanced force
acts on it.
A hockey stick hits a puck on the ice. With respect to Newton’s third
law of motion, identify an action-reaction pair in terms of objects and
forces.
a.
b.
c.
d.
the stick on the puck; the puck on the stick
the stick on the puck; the puck on the ice
the puck on the stick; the stick on the ice
the stick on the ice; the ice on the puck
Newton’s 3rd- for
every action there’s
an equal and
opposite reaction.
Two cars with different masses travel at the same speed down a hill
toward a stop sign. What will happen when both cars apply brakes at
the same time to stop?
a. The car with the smaller mass will require less force to stop than
the car with the larger mass.
b. The car with the larger mass will maintain its velocity while
traveling down the hill.
c. The car with the smaller mass will take longer to stop than the car
with the larger mass.
d. The car with the larger mass will have less inertia than the car with
the smaller mass.
Newton’s 2nd Law- objects with a larger mass are
harder to change their speed or direction
F= m x a

1. Potential & Kinetic Energy- sort each card as Potential or Kinetic
Energy, or both.
2. Sort the cards as to what type of energy they are.
3. Answer the questions:
When a lion eats a zebra and then uses the energy from the zebra to
run, the lion’s body converts —
a.
b.
c.
d.
chemical energy to mechanical energy
electrical energy to chemical energy
chemical energy to light energy
mechanical energy to chemical energy
All food is stored chemical
energy. An animal eats to
get energy so it can movemechanical energy
The diagram below shows a hot air balloon rising. Propane gas tanks
are seen at the bottom of the balloon.
Which vehicle has the greatest
acceleration as it enters the
highway?
a.
b.
c.
d.
Sedan
Coupe
SUV
Truck
An object with less
mass has more
acceleration. The
coupe has the smallest
mass.
Four students raced toy cars on a track. The mass and the
acceleration of each car is recorded in the table below.

Propane- stored chemical energy.
When the propane is lit the chemical energy transform into heat
(thermal energy). Heat causes the air inside the balloon to expand
which makes the balloon move. This is mechanical energy.
