Study Notes
- All Terminology + Formulas
Terms
- Motion: When an object's position changes as time passes
- Position: Where something is located
- Displacement: Change in an object's position from start to end
- Velocity: Displacement over time; speed with direction
- Acceleration: Change in velocity divided by change in time
- Net Force: The sum of all forces acting on an object
- Normal Force: Compression
- Energy: The ability to do work (work is the transfer of energy)
- Polarization: Charges in a neutral object shift, causing on side +, one side -
- Force: A push or pull that changes the motion; F=ma
- Newton's 1st Law: An object at rest stays at rest; an object in motion stays in motion
- Newton's 2nd Law: F=ma
- Newton's 3rd Law: For every action, there is an equal and opposite reaction
- Speed: The rate of movement; distance over time
- Conductor: Allows electricity & heat to flow; example: metal
- Inductor: Hard for electricity & heat to flow; example: glass, rubber, wood
Formulas
- Ff = μ(Fn)
- Elastic Energy: ½kv² → spring
- Kinetic Energy: ½mv² → movement
- Net Force: F=ma
- Velocity: (xf-xi) / (tf-ti)
- Acceleration: (vf-vi) / (tf-ti) → m/s²
- Area of a Triangle: ½(bh)
