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
What is the relationship between mass (m) and velocity (v) in the context of physics?
In physics, the relationship between mass (m) and velocity (v) is described by momentum, which is the product of an object's mass and its velocity. Mathematically, momentum (p) is calculated as p m v. This means that the momentum of an object is directly proportional to both its mass and velocity.
What is the standard units of velocity?
Velocity is speed and its direction. The units of velocity are any unit of speed and any means of indicating a direction.
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.
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'.
How do you calculate Velocity squared?
Velocity squared is calculated by multiplying the velocity of an object by itself. For example, if the velocity of an object is 10 m/s, then the velocity squared would be 10 m/s * 10 m/s = 100 m/s^2.
How is kinetic energy affected by a change in velocity?
Kinetic energy is directly proportional to the square of the velocity of an object. This means that as the velocity of an object increases, its kinetic energy increases exponentially. Conversely, if the velocity decreases, the kinetic energy will decrease accordingly.
What is the uniform velocity of an object that move 602 m East in 250 seconds?
To find the uniform velocity, divide the distance traveled by the time taken. Velocity = Distance / Time Velocity = 602 m / 250 s Velocity = 2.408 m/s Therefore, the uniform velocity of the object moving 602 m East in 250 seconds is 2.408 m/s.
What is the formula to calculate velocity in m/s in the field of physics?
The formula to calculate velocity in meters per second (m/s) in physics is: Velocity (m/s) Distance (m) / Time (s)
What is the change in velocity for each of the following initial and final velocities?
We don't answer questions taken from copyrighted materials.
What is velocity expressed in?
velocity is expressed in 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.
