Draw a picture below that shows an example of a balanced force (examples: a bird’s nest in a tree, a hat on a person’s head, or a light hanging from a ceiling). Show the forces acting on the object.
Equation Sheet. Practice solving for net force, using Newtons second law (F=ma), and relating F=ma to the acceleration equations.
For each of the following problems, give the net force on the block, and the acceleration, including units. 10 N 30 N. For problems 6-9, using the formula net Force = Mass • Acceleration, calculate the net force on the object.
Free-body diagrams for four situations are shown below. In each case, the net force is known, however, the magnitudes of some of the individual forces are not known. Analyze each situation by writing a Fnet equation to determine the magnitude of the unknown forces. F=ma Worksheet.
a) What is the net force if the force of friction between the wagon and the ground is 12 N? b) If she uses 80 N to pull the wagon through a mud puddle, and the net force on the wagon is 38 N, what friction force acts on the wagon?
