Mechanics

Key Definitions

• Motion: Change in position of an object over time
• Distance: The total length of the path traveled
• Displacement: The change in an object's position from the starting point
• Speed: The distance traveled divided by the time taken
• Velocity: The speed of an object in a specific direction

Exam Tips

• Practice calculating speed, velocity, and acceleration from given data
• Understand the differences between distance, displacement, speed, and velocity
• Be able to sketch and interpret displacement-time and velocity-time graphs
