What is the difference between initial velocity and final velocity?
Initial velocity is the velocity an object begins with Final velocity is the velocity at which the object ends up in Say a car is travelling at 13 m/s and then crashes into a wall stopping it it's intitial velocity was 13 m/s and it's final velocity is at 0 m/s or Say a car starts off at 5 m/s but then accelerates from 5 m/s to 10 m/s. It's inital velocity would be 5 m/s but it's resulting or final velocity is 10 m/s
Why can velocity be positive or negitave?
Velocity can be a positive or a negative because velocity is a vector, which means it is also affected by direction. This that if one car is going +10 m/s and another is travelling at -10 m/s, this means that they are travelling the same speed in opposite directions.
What is the difference between constant velocity and average velocity?
The average velocity is trying to find how fast the car is going at an average rate. However, constant velocity means that the car is going at an unchanged velocity. Say a car is going at 75 m/s and then changes to 50 m/s and then changes to 25 m/s in 30 minutes. The car is going at different velocities at different times. To find the average, you simply just add the 3 together, then divide by 3 giving you, 50 m/s In the 30 minutes, it's average velocity was 50 m/s However, for a car going at a constant velocity, it means that the velocity never changes. Say a car is going at a constant velocity for 30 minutes at 50 m/s. In those 30 minutes, the car will never change it's velocity and remain at 50 m/s. Constant means that it doesn't change.
Distinguish between velocity and acceration. Use an example to demonstrate your answer?
Velocity - rate of change of position Acceleration - change in velocity over time A car moving south at 20 m/s south has a constant velocity of 20 m/s southward. Let's assume this car starts to accelerate at 1 m/s2. This means that each and every second, the car's velocity will increase by 1 m/s.
what is the meaning of 5m/s South?
the meaning is 'velocity' ; NOT speed. 5 m/s South , means that the object is moving at a speed of 5 metres per second (m/s) in a southerly(South) direction. When speed and direction are given together it means 'velocity'.
What is velocity expressed in?
velocity is expressed in m/s
Is velocity the slope of the displacement vs time graph?
Velocity=m m=rise/run
Is velocity the slope of the displacement vs. time graph?
Velocity=m m=rise/run
How to convert Angular velocity to velocity?
V=wr Where : V: Linear velocity w: Angular velocity r: Radius v = 600 m/m r=0.75m
What is momentum measured in?
Momentum is mass times velocity (MxV).Mass is in kg and velocity is in m/s.This means that the answer should read kg x m/s.This is not equivalent to newtons which is kg x m/s^2.
What is the velocity of a 2000 kg car possessing 300 kg ms of monmentuem?
Just use the definition of momentum, as mass x velocity. In this case, you need to divide the momentum by the mass, to get the velocity.
Is it possible for a body to have acceleration when moving constant speed and constant velocity?
No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.
