2. Kinematics Flashcards
What is displacement?
Displacement is the distance of an object or a point, in a specific direction, from some reference point.
What is speed?
Speed is a distance travelled divided by the time taken.
What is average speed?
Average speed is the total distance travelled divided by total time taken.
What is velocity?
Velocity is the rate of change of displacement.
What is average velocity?
Average velocity is the total change of displacement divided by the total time taken.
What is acceleration?
Acceleration is the rate of change of velocity.
What is acceleration of free fall?
Acceleration of free fall is the acceleration of a body towards the surface of Earth when the only force acting on its weight.
9.81ms⁻²
What is the kinematic equation not present in formula list?
v = u + at
What is the formula of motion in the presence of air resistance?
downward motion
Fnet = W - Fair resistance
ma = mg - F air resistance
a = g - F air resistance / m
