  • Calculating Final Velocity on a Ramp - Physics Forums
    The original poster outlines a method for calculating theoretical acceleration and velocity based on measurements of distance, time, and mass Some participants suggest alternative methods, including using angles and friction considerations
  • Velocity of an Object Dropped from Height: Law Explained
    The discussion clarifies that the velocity of an object dropped from a height positively correlates with the height due to the Law of Conservation of Energy As an object falls, its potential energy is converted into kinetic energy, resulting in increased velocity with greater height While this principle holds true in a vacuum, it is essential to consider factors such as air resistance and
  • Understanding Zero Velocity and Non-Zero Acceleration: Explained
    The discussion centers on the concept of having zero velocity while experiencing non-zero acceleration, exploring various scenarios and interpretations within the context of physics
  • Numerade
    Confusing speed with velocity, neglecting the directional component of velocity Overlooking that deceleration is still a form of acceleration (negative acceleration) Failing to correctly apply the vector nature of velocity and acceleration in problem-solving
  • Torque Power: Understanding Angular Velocity - Physics Forums
    The discussion revolves around the relationship between torque, power, and angular velocity, particularly in the context of rotating systems Participants explore how torque can exist in systems with constant angular velocity and the implications of this on the understanding of power and friction
  • Diving Board Jump: Analyzing Velocity and Height - Physics Forums
    The problem involves a diver jumping off a 3 00 meter high diving board with an initial upward velocity of 1 75 m s The questions focus on determining the diver's velocity upon reaching the water and the maximum height attained above the water's surface Participants discuss the application of kinematic equations to find the diver's velocity and maximum height There is an exploration of the
  • Does a rotating accelerometer moving linearly measure linear velocity . . .
    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)
  • Why Does a Car Move at Constant Velocity Despite Equal Opposing Forces . . .
    The discussion remains unresolved regarding the initial confusion about the relationship between force, acceleration, and velocity Participants reference Newton's laws, but there are varying interpretations of how these laws apply to the scenario of a car moving at constant velocity against opposing forces
  • How Long Does It Take a Person to Reach Terminal Velocity?
    A later reply proposes an estimate of terminal velocity at around 120 mph for a person in random positions and acknowledges the simplicity of modeling speed, distance, and time once terminal velocity is reached, while questioning how to model the approach to terminal velocity
  • Velocity Ratio, mechanical advantage, Efficiency of a screw jack
    The Velocity Ratio is calculated as VR = 94 2 using a lead screw of 12 mm and a radius of 180 mm The Mechanical Advantage is determined to be 24 51, based on a load of 200 kg converted to Newtons
