Spring compressed, find velocity. - Physics Forums
2011年2月8日 · The velocity of a compressed spring can be calculated using the equation v = √(kx 2 /m), where v is the velocity, k is the spring constant, x is the displacement of the spring from its equilibrium position, and m is the mass of the object attached to the spring.
Finding the velocity at the top of a loop - Physics Forums
2014年6月17日 · The velocity at the top of a loop can be calculated using the formula v = √(rg), where v is the velocity, r is the radius of the loop, and g is the acceleration due to gravity. Does the mass of the object affect the velocity at the top of a loop? No, the mass of the object does not affect the velocity at the top of a loop.
Understanding Zero Velocity and Non-Zero Acceleration: Explained
2009年8月1日 · In summary, the conversation is discussing the concept of zero velocity and non-zero acceleration. It is clarified that this situation can occur when an object is thrown vertically upwards and reaches the top of its trajectory, as well as in other situations such as a boat accelerating against a river current or a plane being overtaken by a faster plane.
Find Velocity given Force and Mass - Physics Forums
2009年3月17日 · The relationship between force, mass, and velocity is defined by Newton's Second Law of Motion, which states that Force = Mass × Acceleration (F = ma). To find velocity, you need to integrate acceleration over time, as velocity is the integral of acceleration. How can you calculate velocity if you know the force and mass?
Understanding Non-Zero Velocity vs. Non-Zero Acceleration
2011年9月22日 · Non-zero velocity and acceleration are closely related. Acceleration is the rate at which an object's velocity changes. If an object has a non-zero velocity, it means it is moving at a certain speed and direction. Any change in speed or direction would result in a change in velocity, and therefore, acceleration.
Explaining Velocity Increase on Ramp: Gravity & Slope - Physics …
2007年3月3日 · FAQ: Explaining Velocity Increase on Ramp: Gravity & Slope What is velocity? Velocity is a measure of an object's speed and direction of motion. It is a vector quantity, meaning it has both magnitude (speed) and direction. How is velocity affected by gravity on a ramp? Gravity plays a major role in determining the velocity of an object on a ramp.
Coulomb's Law: Determining the velocity of a charge when far apart
2011年2月26日 · As a result, the velocity of the charged particle will also decrease as the distance increases. Can Coulomb's Law be applied to moving charges? Yes, Coulomb's Law can be applied to moving charges. However, it becomes more complex as the motion of the charges must also be considered in the calculation of the force and velocity.
Derivation of velocity in nth Bohr orbit - Physics Forums
2011年3月17日 · The velocity in the nth Bohr orbit is derived using the formula v = (Z/n) * (e^2/4πε0) * (1/n - 1/m), where Z is the atomic number, n is the principal quantum number of the orbit, e is the elementary charge, ε0 is the permittivity of free space, and m …
Finding velocities in F vs x graph - Physics Forums
2010年6月23日 · The slope of the velocity vs time graph represents the change in velocity over the change in time, which is equal to the acceleration. What other information can be obtained from a F vs x graph? In addition to velocities and accelerations, a F vs x graph can also provide information about the displacement, force, and energy of an object.
Determine the minimum initial velocity - Physics Forums
2014年2月1日 · The minimum initial velocity is the lowest speed at which an object must be launched in order to reach a specific distance or height. How is the minimum initial velocity determined? The minimum initial velocity is determined by using the equations of motion, specifically the equation for displacement (s = ut + 1/2at^2) and the equation for ...
