A rolling ball has an initial velocity of 5 meters per second 30 seconds later its velocity is 2 meters per second What is the acceleration of the ball?
The acceleration of the ball can be easily found using the kinematic equation if = vi + at. Where vi = initial velocity, if = final velocity, a = acceleration, and t = seconds. The acceleration is -0.1 m/s^2.
What is molecular velocity in chem?
Molecular velocity is defined as the velocity of a each molecule in a certain sample of gas. It can be expressed by means of root-mean-square velocity, average velocity and most probable velocity.
Is momentum a vector?
Momentum is a vector quantity because the definition of momentum is that it is an object's mass multiplied by velocity. Velocity is a vector quantity that has direction and the mass is scalar. When you multiply a vector by a scalar, it will result in a vector quantity.
Electrons and protons in a magnetic field?
The proton behaves in the opposite direction of the electron in a magnetic field. bcz the magnetic field is due to motion of electrons in a conductor nd protons are +vely charged so it will be attracted by the magnetic field and so proton move in opposite direction to the electron i.e in anticlockwise direction
What is the velocity of an electron with a mass of 9.11 x 10-31 kg at a position with an uncertainty of 5x10-10 m?
Do you mean the free mean path velocity, or the absolute velocity over a specific distance (molecular diffusion)?
How is velocity same from instantaneous speed?
Instantaneous speed is the magnitude of the velocity. Velocity also states the [direction] of the speed.
What is the formula of velocity?
There are several definitions. not just one. Average velocity in a direction = Average displacement (distance) in that direction/time Instantaneous velocity in a direction = derivative of displacement in that direction with respect to time Average velocity in a direction = Initial velocity in that direction + Average acceleration in that direction * time Instantaneous velocity in a direction = Definite integral of acceleration in that direction with respect to time, with initial velocity at t = 0 Then there are others in which time is eliminated.
What is the difference between instantaneous velocity and instantaneous speed?
Speed, instantaneous or not, is a term used for how fast an object travels. Velocity, instantaneous or not, is a term used for how fast an object travels in a particular direction.
What are the difference of instantaneous velocity and average velocity?
Average velocity in a direction is calculated as the displacement in that direction divided by the total time taken. As the time interval is reduced, the displacement over that period also reduces and the limiting value of that ratio is the instantaneous velocity.
What's the difference between instantaneous velocity and instantaneous acceleration?
Instantaneous velocity is the rate at which an object is moving in a uniform direction, distance per unit time, at any given instant in time. instantaneous acceleration is the rate at which an object's velocity is changing at any given instant in time
Is instantaneous velocity a vector quantity?
YES!!! Because velocity is speed in a given direction(vector). e.g 30 mph is a scalar quantity, but '30 mph in a northerly direction' is a vector quantity, because it has direction.
What is the speed of an object in a certain direction?
Speed is distance/time or distance per unit of time. It is velocity that is distance/time in a given direction. Velocity can be said to be speed in a certain direction.
Is the magnitude of instantaneous velocity always equal to the instantaneous speed?
Because speed is the magnitude of the velocity vector. The velocity consists of the speed and the direction, and the whole thing can be embodied in a 3D vector. If you like the velocity is the magnitude (the speed), which is a scalar (just a real number), multiplied by a unit vector in the right direction.
Does the speedometerof a car read average speed or instantaneous speed?
The speedometer in a car does not measure the car's velocity because velocity is an (A) vector quantity and has a direction associated with it (B) vector quantity and does not have a direction associated with it.
What is a instantaneous velocity?
Instantaneous velocity: The velocity of an object at one moment in time.
How do you find overall velocity?
There is average velocity, and there is instantaneous velocity. I don't think "overall velocity" is a concept generally used in physics; please clarify what you mean.
Does a speedmeter give instantaneous speed or velocity?
Velocity is a vector quantity, so a different direction makes a different velocity. Speed is a scalar quantity, where direction makes no difference. Since a speedometer reads the same regardless of direction of motion, it is providing speed, not velocity.
