Movement And Position
Gbogbo ọrọ náà
How fast is it going? Is it speeding up or slowing down? How far will it travel? These are the questions that launched physics as a science, and they are still the ones you will answer most often in your Edexcel exam. This topic gives you the language and the equations to describe any straight-line motion precisely.
You will learn to read and draw distance-time and velocity-time graphs, calculate speed and acceleration from first principles, and use the key equations - including the powerful relationship between final speed, initial speed, acceleration and distance. Every worked example uses the method examiners reward: state the equation, substitute, solve, and check units.
Ebumnobi
- Plot and explain distance-time graphs
- Know and use the relationship between average speed, distance moved and time taken: average speed = distance moved / 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: acceleration = change in velocity / time taken, a = (v - u) / t
- 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: v2 = u2 + (2 x a x s)
