Velocity means speed and direction. So if you know the speed, all you need to add is the direction of motion and you will have the velocity.
The velocity of the car in this case is changing (to specify velocity, you indicate a speed and a direction), therefore the car is accelerating.The velocity of the car in this case is changing (to specify velocity, you indicate a speed and a direction), therefore the car is accelerating.The velocity of the car in this case is changing (to specify velocity, you indicate a speed and a direction), therefore the car is accelerating.The velocity of the car in this case is changing (to specify velocity, you indicate a speed and a direction), therefore the car is accelerating.
The speed of the car. The speed-o-meter only shows a magnitude ( or a number ) and to tell the velocity of a car it would have to give that speed some direction. Since the speedometer assigns no direction to the car, the number assigned as the speed of the car cannot be the velocity of the car.
Velocity means speed and direction. For example you could say that a car's velocity was 60 miles per hour northwards.
Just the speed of the car.
The velocity of light coming from a cars lights will be the speed of light C in the substance in front of the lights. It wont be the speed of light+the speed of the car however.
Velocity changes as direction is continuously changing.
To change the acceleration of a car: speed up, slow down or turn. Acceleration is any change in velocity. Velocity is "how fast" and in "what direction". To speed up is to accelerate (increase the velocity). To slow down is to deaccelerate (decrease the velocity) To turn is also a form of acceleration (changes the direction of the velocity).
Velocity includes direction. For example, "the car is driving 100 km/h" refers to speed, whereas, "the car is driving 100 km/h [North]" is velocity
Constant speed around a curve is changing velocity.
No. It's confusing unless you're into physics or mathematics but velocity is a vector quantity with speed is one aspect. Velocity includes speed and the direction of motion. A car is going 60 miles per hour as speed. A car is going 60 MPH due north is velocity.
No, it is not. Basically speed is a scalar whereas velocity is a vector.A car going round a circular track at constant speed has a velocity which is changing at every moment.
