If you know the initial linear velocity and orientation, and keep track of the linear acceleration (accelerometer) and angular velocity (gyroscope), then you can calculate linear velocity by integration. It's simple in theory, but tricky in practice, because small initial errors add up over time (drift).
This video explains how the direction and gradient of a line on a velocity-time graph can tell us whether an object is accelerating, moving at a constant velocity or decelerating. Velocity time graphs ...
Displacement close displacementA distance measured in a specified direction. is the distance moved in a straight line, in a given direction, from the starting point. Displacement = 24 m east. Velocity ...
Acceleration close accelerationThe rate of change in speed (or velocity) is measured in metres per second squared. Acceleration = change of velocity รท time taken. is the rate of change of velocity. It ...
Velocity-time graphs show how the velocity (or speed) of a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, decelerating, or still.
The discussion revolves around the concepts of velocity and acceleration vectors, particularly focusing on how to calculate acceleration from two velocity vectors and the interpretation of vector components. Participants explore the differences in vector addition and subtraction methods, as well as the implications of vector direction in motion.
The discussion revolves around calculating the Reynolds number when the particle velocity is unknown, particularly in the context of determining particle settling velocity in a fluid. Participants explore the relationship between Reynolds number, terminal velocity, and the conditions under which laminar or turbulent flow occurs. One participant seeks clarification on how to calculate the ...
