Movement And Position
Bayani Gaba-gaba
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.
Manufura
- 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)
