What to Focus On
- Aristotle’s view is flawed.
- Friction explains why moving bodies usually slow down.
- Galileo established the law of inertia.
- Zero net external force means zero acceleration.
- Uniform motion and rest both correspond to zero acceleration.
- Normal reaction is a self-adjusting force.
- Momentum is p = mv.
- Momentum is a vector quantity.
- Second law: force equals rate of change of momentum.
Common Mistakes to Avoid
A body needs a force to keep moving with uniform velocity.
If a body is momentarily at rest, the force on it must be zero.
Weight and normal reaction are always an action-reaction pair.
Memory Tips
Aristotle's flawed view of motion
Law of inertia
Newton's first law
