Kinematics in two dimensions
Apply kinematics to 2D motion including projectiles; use vectors for displacement, velocity and acceleration
What you'll learn
- 1
Imagine a ball rolling across a flat table. It moves both forward and sideways at the same time. That's motion in TWO directions!
- 2
How many directions does something move in when it's in TWO dimensions?
- 3
Here's a ball moving diagonally: it's going 3 m/s right and 4 m/s up. Its total speed is the diagonal of the triangle formed by these arrows.
- 4
A ball rolls 3 m/s east and 4 m/s north. What is its overall speed?
- 5
Drag the ball so it moves 6 m/s right and 8 m/s up. What's the total speed?
- 6
If a ball moves 5 m/s right and 12 m/s up, what is its total speed?
- 7
In two dimensions, which two things are completely independent?
