What you'll learn

  • how to interpret distance- time and speed- time graphs
  • how to calculate speed and distance

Course content

1 section • 12 lectures • 1h 15m total length

  • Outline0:52

    Explore motion in one dimension by examining speed, displacement, and acceleration, and how these concepts describe straight-line movement.

  • Speed6:17

    Define speed as distance per unit time, using meters per second, and examine constant, increasing, and decreasing speed with a speed-time graph.

  • Velocity2:26

    Differentiate speed and velocity: speed is a scalar, velocity a vector, the rate of displacement change with time. When displacement returns to start, velocity is zero while speed remains nonzero.

  • Displacement10:43

    Explain displacement as the net change in position, final minus initial, and relate it to speed, velocity, and time through displacement-time and speed-time graphs.

  • Speed vs Time Graph4:03

    Compare constant and changing speeds using speed-time graphs and displacement-time graphs, showing how displacement grows with time at set speeds and with varying speeds.

  • Acceleration10:27

    Define acceleration as the rate of change of velocity with time, with units of meters per second squared, and illustrate constant positive and negative acceleration using velocity-time and acceleration-time graphs.

  • Deceleration3:09

    Define deceleration as negative acceleration and explain how acceleration, a vector, indicates speeding up or slowing down in different directions and initial velocities.

  • Acceleration on Simulation3:23

    Watch how acceleration changes motion in a physics simulation, linking position, velocity, and time while contrasting constant velocity with varying acceleration and related graphs.

  • Question Solving about speed and displacement10:06

    Analyze distance-time and speed-time graphs to understand a motorcycle's motion, including pauses, acceleration phases, constant speed, maximum speed, and total distance calculations.

  • Question Solving About Acceleration6:46

    Analyze acceleration and deceleration in a shuttle bus braking with uniform -4.1 m/s^2 from 90 m/s to rest, and calculate stopping time.

  • Motion in One Dimension7:20

    this lecture covers motion in one dimension under constant acceleration, presenting v = v0 + a t and Δx = v0 t + 1/2 a t^2.

  • Question Solving About Motion in One Dimension9:41

    Apply constant-acceleration kinematics to one-dimensional motion, relating initial and final velocities to time and displacement. Analyze scenarios like car acceleration, skateboard motion, and a camera falling from height.

Requirements

  • How to measure time
  • How to Measure Length

Description

Before this lesson, students must finish measurement unit. 

In this lecture, they will able to define speed, velocity, displacement, acceleration and gravitational acceleration.

Students will be able to draw graph of speed, displacement and acceleration depending on time. Moreover, they will be able to summarise displacement from speed vs time graph, and speed from acceleration vs time graph. They will be able to convert graphs.

In this lesson, we covered free fall. They will be able to make calculation about speed displacement and acceleration. They will deal with formulas, make calculations with numbers.

For IB and AP students, we covered motion in one dimension; however, we did not cover force. They will deal with acceleration without force.

Who this course is for:

  • All Science Students
  • IGCSE students
