Force Calculations
DIRECTIONS: For each question, use the F = m X a formula to solve for force, mass, or
acceleration. If needed, draw a force diagram. Show your work and include units.
1. An object with a mass of 62 kg is observed to accelerate at the rate of 2 m/s2. Calculate the
force required.
2. A force of 18 N acts upon a 7 kg block. Calculate the acceleration of the object.
3. Sally pushes a shopping cart to the left with 120 N of force at an acceleration of 4.5 m/s2. What
is the mass of the shopping cart?
Drawing Forces Practice
*Diagram the forces acting on each object in the scenarios below. Remember to take into
account the magnitude (amount) of the force. For each question, state whether the forces
are balanced or unbalanced.
1. A binder is pulled from the left and moves across the desk.
2. A cup of coffee rests on the counter.
3. A skydiver is free-falling at a constant velocity toward the valley below.
Direction: Read the following question and circle the correct answer. If needed, draw a picture to
help you answer the question.
1. Tugboat A is pulling with 500 Newtons of force in an eastern direction. If another tugboat
is attached and starts pulling to the west with a force of 300 Newtons, what change will
occur in the motion of Tugboat A?
A. Tugboat A will move east faster
B. Tugboat A will move east more slowly
C. Tugboat A will start moving west
D. Tugboat A will stop moving
