STATION 3: Force Calculation Practice
Please Answer the questions below.
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? ______________________

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×v
Where... p = momentum (in kg·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·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·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
