Revision Notes — Motion in a Plane
Key concepts, formulas, and definitions from Motion in a Plane for BCECE Physics preparation.
Key Topics to Revise
Scalars and Vectors
- Scalars have only magnitude (distance, speed, temperature, mass)
- Vectors have both magnitude and direction (displacement, velocity, acceleration, force)
- Vector representation: Arrow with length = magnitude, arrow direction = vector direction
Vector Operations and Resolution
- Triangle law: If two vectors form two sides of triangle, third side gives resultant
- Parallelogram law: Two adjacent sides of parallelogram give resultant as diagonal
- Vector addition is commutative: A⃗ + B⃗ = B⃗ + A⃗
Motion in a Plane - Kinematics
- Position vector r⃗(t) describes location of particle at time t
- Velocity v⃗ = dr⃗/dt is always tangent to the path
- Average velocity = Δr⃗/Δt depends only on displacement
Motion with Constant Acceleration
- Constant acceleration means both magnitude and direction of a⃗ remain fixed
- Motion equations apply independently to x and y components
- Trajectory depends on initial velocity and acceleration vectors
