Displacement and Velocity Lesson 5 Objects in Motion

DISPLACEMENT o o o Suppose you are taken a trip from Memphis to Nashville The trip may several hours or many days The straight-line distance between your beginning point and ending point will be the same. 1/17/2022 http: //mrabynum. weebly. com 2

DISPLACEMENT o Displacement is the change in position of an object n n n 1/17/2022 The concept displacement is usually describe an object has moved When an object is at rest, the displacement is zero A displacement to the right indicate a positive displacement A displacement to the left indicate a negative displacement A displacement up or down is positive or negative respectively http: //mrabynum. weebly. com 3

DISPLACEMENT o o The mathematically definition of displacement is X = Xf - XI Where: X = displacement Xf = Final Position XI 1/17/2022 = Initial position http: //mrabynum. weebly. com 4

DISPLACEMENT Example: A car left Memphis to Nashville, the distance from Memphis to Nashville is 200 miles. What is the displacement of the car? 1/17/2022 http: //mrabynum. weebly. com 5

DISPLACEMENT 1. 2. 3. Problem solved Choose the appropriate formula X = X f - XI Substitute correct number in the formula. X = 200 mi – 0 mi 4. X = 200 mi 1/17/2022 http: //mrabynum. weebly. com 6

DISPLACEMENT o o o 1/17/2022 Tips To Remember: Displacement is a quantity with both magnitude and direction In a one-dimensional motion, there are only two directions an object can move, they are negative and positive. Displacement sometime negative if final position is smaller than initial position. http: //mrabynum. weebly. com 7

DISPLACEMENT Summative Assessment Instructions: Calculate the displacement of the following problems: 1. How far did the horse travel if it traveled from a position of 200 m to a position of 500 m? 1/17/2022 http: //mrabynum. weebly. com 8

DISPLACEMENT 2. What would be the displacement of a football running back that was on the 50 yard line and ran to the 20 yard line. 3. What is the displacement of an object that moves 80 cm to the left and then 20 cm to the right? 1/17/2022 http: //mrabynum. weebly. com 9

DISPLACEMENT 4. 5. What will the displacement of an object that moves 80 cm to the left and then 20 cm to the right? A basketball player ran down the court traveling a distance of 30 km and then returned to the same sport of the floor. How far did he travel? 1/17/2022 http: //mrabynum. weebly. com 10

DISPLACEMENT 6. 7. 8. 9. A bus left a small town traveling south for 50 miles. How far did he travel? If a object moves to the left, what kind of displacement would it have? A ball travels 100 m, then back 90 m. How far did it travel? Define displacment. 1/17/2022 http: //mrabynum. weebly. com 11
