Movement And Position
Akopọ
Understanding how objects move is the foundation of all mechanics. Whether you are tracking a sprinter on a track or a car on a highway, the same equations and graphs describe the motion.
In this lesson you will learn how to calculate speed and acceleration, read and plot distance-time and velocity-time graphs, and use the equations of motion to solve problems about objects that speed up, slow down or move at constant velocity.
Awọn Afojusun
- Plot and explain distance-time graphs
- Know and use the relationship between average speed, distance moved and time taken
- Investigate the motion of everyday objects such as toy cars or tennis balls
- Know and use the relationship between acceleration, change in velocity and time taken
- Plot and explain velocity-time graphs
- Determine acceleration from the gradient of a velocity-time graph
- Determine the distance travelled from the area between a velocity-time graph and the time axis
- Use the relationship between final speed, initial speed, acceleration and distance moved
