Study Notes
Acceleration
- Defined as the rate of change of velocity, influenced by all forces acting on an object.
- Formula: a = (v final - v initial) / (t final - t initial).
- Measured in metres per second squared (m/s²).
Average Acceleration
- Calculated as the change in velocity over an elapsed time.
Constant Acceleration
- Occurs when an object's velocity remains unchanged during a time period.
Velocity
- A vector quantity that includes both magnitude and direction.
- Measured in meters per second (m/s).
Average Velocity
- Determined by dividing displacement by the time taken.
Velocity vs Time Graph
- Represents velocity (in m/s) on the y-axis; slope indicates acceleration.
- Similar in structure to position vs time graphs.
Free Fall
- The motion of a body solely affected by its weight, without any other forces acting on it.
Gravity
- The universal force of attraction between all masses; near Earth's surface, its approximate value is 9.8 m/s² (often rounded to 10 m/s²).
Velocity Equation
- Expressed as v = at, where v is velocity, a is acceleration, and t is time.
Displacement Equation
- Given by d = 1/2(at²), relating displacement (d) to acceleration (a) and time (t).
Constant Velocity
- Characterizes motion where an object covers equal distances in equal time intervals.
Weight
- Defined as the force due to gravity acting on an object, calculated with w = mg (mass × acceleration due to gravity).
- Measured in newtons (N) as a unit of force.
Displacement
- A vector quantity reflecting the overall change in position of an object, or the difference between final and initial positions.
Motion Graphs or Diagrams
- Visual representations of an object's movement that illustrate position, velocity, and acceleration at key points in time.
