Read each question carefully and draw a free body diagram for the object(s) in question. Label all forces clearly and indicate the direction of acceleration where applicable. Provide explanations for your answers.
1. What is the primary purpose of drawing a free body diagram in physics?
2. The force exerted by a surface perpendicular to the surface of contact is called the force.
3. The force that opposes motion between two surfaces in contact is known as .
4. A block of mass 'm' is resting on a frictionless inclined plane at an angle 'θ' to the horizontal. Draw a free body diagram for the block.
5. Which of the following forces is not considered a contact force?
Tension
Friction
Gravity
Normal Force
6. In a free body diagram, the length of an arrow representing a force indicates its magnitude.
True
False
7. A 10 kg block is pulled horizontally across a rough surface by a rope with a tension of 50 N. If the coefficient of kinetic friction is 0.2, draw a free body diagram for the block and calculate the net force acting on it. (Assume g = 9.8 m/s²)
