Study Notes
- Inertia refers to an object's tendency to resist changes in its motion.
- Motion is an object's change in position relative to a reference point.
- A reference point is a place or object used to determine if something is in motion.
- Acceleration is the rate at which velocity changes.
- Force constitutes a push or a pull.
- Net force is the combination of all forces acting on an object.
- Velocity is speed in a given direction.
- Static friction acts on objects that are not moving.
- Rolling friction occurs when an object rolls over a surface.
- Sliding friction occurs when one solid surface slides over another.
- Gravity is a force of attraction between objects due to their masses.
- Mass is the amount of matter in an object.
Newton's Laws
- Newton's First Law states that an object at rest stays at rest, and an object in motion stays in motion with the same speed and direction unless acted upon by an unbalanced force.
- Newton's Second Law states that force equals mass times acceleration.
- Newton's Third Law states that for every action, there is an equal and opposite reaction.
Momentum and Weight
- Conservation of momentum means that the total momentum of a system of objects remains constant if no outside forces act on the system.
- Weight is a measure of the force of gravity on an object.
- A vector is a quantity possessing both size and direction.
- Electromagnetic force causes attraction between electrons and the positive nucleus; all forces between atoms are caused by it.
- A system is a group of related things or parts that work together as a whole, built to produce one or more specific goals.
Formulas
- Force is calculated as mass multiplied by acceleration, measured in Newtons.
- Acceleration is calculated as (final velocity - initial velocity) / time.
- Astrodynamics involves the study of mechanics used in space.
