1. Motion By: Alyssa Mae M. Antonio, LPT. INSPIRED BY

2. Any physical movement or change in position or place, relative to a reference point. What is motion?

3. Identify the linear and angular quantities used to describe translational and rotational motion; Compare and contrast translational and rotational motion; Learning Outcomes

4. Motion is typically described in terms of displacement, distance (scalar), velocity, acceleration, time and speed. MOTION The change of position of an object with respect to time.

5. When a body moves along a straight line path. It is also called as Linear Motion. MOTION The change of position of an object with respect to time.

6. Movement along a straight path, like walking forward or a car driving down a road. Translational motion The important parameters required to study the motion along a straight line are position, distance, velocity, acceleration.

7. The length of the path traversed by a body is called travelled by it. Distance

8. The shortest distance from the initial to the final position of the body. It is the change in position of an object from one point to another. Displacement

9. Refers to physical properties or measurements that describe linear motion or straight-line movement. Examples include: A car travels 250 km. An object moves 5 m east. A runner runs at 8 km/hour. A train travels 100 km/h north. Linear Quantities

10. ROTATION AROUND A POINT OR AXIS, LIKE A SPINNING WHEEL OR OPENING A DOOR. Rotates around a central point. Also called rotational motion. Angular motion

11. REFERS TO THE MOVEMENT ALONG A CRUVED PATH, WHERE AN OBJECT CHANGES DIRECTION CONTINUOUSLY. Movement along a curved path Curvilinear motion

12. Machine that uses motion

13. Elevators A device or machine that transports people or goods between floors in a building.

14. Conveyor belts A continuous loop of material, typically made of rubber, plastic, metal or fabric, that moves along a series of rollers or pulleys.

15. Printing press A machine that produces printed materials, such as books, newspapers, magazines, and more.

16. Wheels and Axles A simple machine that reduces friction and enables efficient movement.

17. Drilling machines A power tool or machine used to create holes in various materials, such as, wood, metal, plastic, masonry.

18. Robotics Robot arms move in curved paths to perform tasks like assembly, welding, or material handling.

19. 1. A power tool or machine used to create holes in various materials, such as, wood, metal, plastic, masonry. 2. Its rotation around a point or axis, like a spinning wheel or opening a door. 3. __________ typically described in terms of displacement, distance (scalar), velocity, acceleration, time and speed. 4. Movement along a straight path, like walking forward or a car driving down a road. 5. The length of the path traversed by a body is called travelled by it. 6. It refers to the movement along a cruved path, where an object changes direction continuously. 7. A car travels 250 km. 8. An object moves 5 m east. 9. A runner runs at 8 km/hour. 10. A train travels 100 km/h north. Quiz:
