Test your understanding of free-body diagrams with 5 practice questions.
Practice Questions
Question 1
A 3 kg block is resting on a horizontal surface. If a horizontal force of 15 N is applied to the block and it does not move, what can be concluded about the forces acting on it?
Question 2
In a free-body diagram, if the gravitational force acting on an object is represented as 50 N downward, what does this indicate about the object's weight?
Question 3
A block is sliding down a frictionless inclined plane at an angle of 30 degrees. What is the net force acting on the block if its mass is 5 kg?
Question 4
When constructing a free-body diagram for an object on an inclined plane, which forces must be included?
Question 5
If a 10 kg object is hanging from a rope and accelerating upwards at 2 m/s², what is the tension in the rope? (Assume g = 9.8 m/s²)
