Study Notes
Motion and Acceleration
- Motion is a change in an object's position relative to a reference point.
- Acceleration is a change in velocity.
- Velocity combines speed and direction.
- Constant speed does not imply constant velocity (changing direction = acceleration).
Examples of Acceleration
- Changing speed (speeding up or slowing down).
- Changing direction.
Reference Point
- A reference point is a stationary object used to determine if something is moving.
- Examples include the sun, a tree, or a building.
Speed and Velocity
- Speed is how fast an object is moving.
- Velocity is speed in a given direction.
- Speed is calculated as distance over time (Speed = distance ÷ time).
Newton's First Law of Motion
- An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force (inertia).
- Examples of this include things like objects remaining in place or objects continuing motion until an action changes the motion.
