The Force Vector What is Force? Types of Forces Contact Forces Field Forces Forces to consider in diagrams https://www.youtube.com/watch?v=b Intro to Vector OIe0DIMbI8&t=3s Draw a scaled diagram of a vector that represents a force of 200 N towards east. Free-body Diagrams https://www.youtube.com/watch?v=aJc 4DEkSq4I&t=4s Free-body diagrams ◼A free-body diagram is a diagram that uses vectors to show all of the external forces acting on an object. ◼A free-body diagram of a book shows only the forces acting on the book. We do We do Draw a free-body diagram for elephant You do Draw a free-body diagram for backpack resting on the floor Draw a free-body diagram for the students Draw a free-body diagram for the person Draw a free-body diagram for the cylinder Draw a free-body diagram for the cart You drag a heavy box to the left across a rough carpet. The box accelerates to the left. Below is a free-body diagram. Which scenario best matches it? a. A rocket accelerating upwards into the sky. b. A book at rest on a tabletop. c. An acorn falling from an oak tree. Below is a free-body diagram. Which scenario best matches it? a. A football flies through the air towards its peak after being punted. b. A skater coasts to a stop in the rightward direction. c. A book accelerates to the right while being pushed rightward across a rough desktop. A rock is free-falling after being dropped from a cliff. Neglect air resistance. Which of the following shows what the free-body diagram should look like? A sky diver is falling with a constant velocity. Considering air resistance, which of the following shows what the free-body diagram should look like? A force is applied to the right to drag a sled across loosely packed snow. The sled accelerates to the right. Which of the following shows what the free- body diagram should look like? A monkey hangs motionless by one arm from a tree branch. Draw the free-body diagram. A hockey puck glides to the left on the ice and slows down. Draw the free-body diagram.
