Worksheet 3 Newton’s 3rd Law Answer Key: ACTION-REACTION FORCES 1. Answer: Since the tension in the rope is equal for both teams, its the force of friction on their feet that wins the tug of war. For the team that pushes forward on the ground with the largest force, the ground pushes back and moves them away
Types of Problems On These Worksheets. Identifying Types of Forces – These problems will present different scenarios, and students will need to determine the type of force at work. For example, “When you pull a door open, what kind of force are you using?” The answer is a “pulling force”.
Figure 3 shows a force of 200 N acting at the end of a plank of wood. The force acts at right angles to the plank and at 3.0 m away from a pivot. Calculate the moment of the 200 N force about the pivot. State the unit of the moment of the force. Use the equation . moment of a force = force × distance at right angles to the direction of the ...

PHYSICS 11 FORCES & NEWTON’S LAWS WORKSHEET 3 1. A 2.5 kg block has a force of sliding friction between it and a level surface of 3.5 N. This block is pulled by an applied force of 14 N. a) Find the coefficient of sliding friction between block and surface. b) What is the unbalanced force as the block is moved?
Drawing Free-Body Diagrams. Meaning of Net Force. Free-body diagrams are diagrams used to show the relative magnitude and direction of all forces acting upon an object in a given situation. A free-body diagram is a special example of the vector diagrams that were discussed in an earlier unit.
A force is a push or pull resulting from an interaction between two objects. Whenever there is a force, there are two objects involved - with both objects pushing (or pulling) on each other in opposite directions.
