Force, Friction and Newton's Laws Review Stations
STATION 2: Draw a comic that illustrates Newton’s first law of motion. Think of the best
scene you can that illustrates this concept. See page 51 for more information on
Newton’s first law of motion.
STATION 3: Force Calculation Practice
force = mass • acceleration
1. An object with a mass of 2.0 kg accelerates 2.0 m/s2 when an unknown force is
applied to it. What is the amount of the force? ______________________
2. An object with a mass of 5.0 kg accelerates 8.0 m/s2 when an unknown force is
applied to it. What is the amount of the force? ______________________
3. An object with a mass of 1500 g (grams) accelerates 10.0 m/s2 when an unknown
force is applied to it. What is the amount of the force? ______________________
4. An object with a mass of 6.0 kg accelerates 4.0 m/s2 when an unknown force is
applied to it. What is the amount of the force? ______________________
5. An object with a mass of 7.5 kg accelerates 8.3 m/s2 when an unknown force is
applied to it. What is the amount of the force? ______________________
7. Aliya kicks a soccer ball with a mass of 0.5 kg. It accelerates with a rate of 5 m/s2.
What is the force she kicks the ball with?_______________
a. Doktor Kaboom kicks a bowling ball with a mass of 5 kg. It accelerates at 2 m/s2.

STATION 5: Momentum Math Practice
MOMENTUM WORD PROBLEMS
Momentum is a measure of how hard it is to stop a moving object, and it is the product
of an object’s
mass and velocity. The equation for momentum is shown below:
p=m&times;v
Where... p = momentum (in kg&middot;m/s), m = mass (in kg), and v = velocity (in m/s)
SHOW WORK
1. Calculate the momentum of a 0.145 kg baseball being thrown at a speed of 40.0
m/s.
2. If a 6.0 kg bowling ball is rolled with a velocity of 3.5 m/s, what is the momentum
of the ball?
3. Which has more momentum, a 3.0 kg mass moving at 9.0 m/s or a 5.0 kg mass
moving at 5.0 m/s?
4. A bicycle has a momentum of 25.00 kg&middot;m/s and a velocity of 2.5 m/s. What is the
bicycle’s mass?
5. What is the velocity of a 0.5 kg ball that has a momentum of 3.00 kg&middot;m/s?
6. An 8000.0 kg truck starts off from rest and reaches a velocity of 18.0 m/s in 6.00
seconds. What is the truck’s acceleration and how much momentum does it have
after it has reached this final velocity?
STATION 6: Science Riddles
We’ve talked about the answers to all of these at some point in time. Try to get as many
as you can
1. You cannot see me, I cannot be touched, you cannot feel me but I can cook your
lunch. What am I?
2. What is a Priest's favorite part about Physics?
3. Which is heavier, a pound of feathers or a pound of bricks?
4. I can rush, I can be hot, I can be cold, I can be hard, I can slip through anything.
What am I?
5. It is impossible for me to be created, and I can never be destroyed, I can only
change form. What am I?
6. You can't see me, but I can see right through you. Especially when you are hurt.
What am I?
7. What can eat a lot of iron without getting sick?
8. What can be measured but has no width, length or height?
9. Give me food and I will live. Give me water and I will die. What am I?
10. In space I’m massive and solid as rock, on earth (at room temperature) I am a
little puddle. What am I?
11. I am a gas and line-up with neon. I am also the home of a superhero. What am I?
