What happens to speed and velocity when a car turns but maintains the same speed?
When a car turns but maintains the same speed, the velocity of the car changes because velocity includes both speed and direction. The speed of the car stays the same, but the direction of the velocity changes as the car turns.
Does the reading of a speedo meter of a car show the speed or velocity of a car?
The reading of a speedometer in a car shows the speed of the car, not the velocity. Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes the speed and the direction of motion.
If a car is traveling at a constant speed but is going around a curve what can you say about the cars motion?
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.
Why is the speed of a car a magnitude of its velocity?
Speed is a scalar quantity that represents the magnitude of velocity, which is a vector quantity. Velocity includes both the speed and direction of an object's motion. Consequently, when discussing the speed of a car, we are only concerned with the magnitude of its velocity, not its direction.
Does the reading of the speedometer of a car show the speed or velocity of the car?
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.
Can a car move with changing velocity while maintaining constant speed?
No, if a car is changing velocity, it is not maintaining a constant speed. Velocity includes both the speed and direction of an object's motion, so any change in velocity would involve a change in speed, direction, or both.
What is the velocity of car light?
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.
What has to happen to a car's acceleration and velocity for a car's speed to increase and have a positive acceleration?
For a car's speed to increase and have a positive acceleration, the car's velocity needs to be increasing in the same direction as its acceleration. This means that the car is speeding up. When the velocity and acceleration have the same sign (both positive or both negative), the car's speed will increase.
How is it possible for a moving car velocity to change but the speed to stay constant?
Velocity is a vector (has a size and a direction) but speed is a scalar (just a number). The velocity is therefore given by the speed and the direction the speed is going. If you change the direction but continue at the same rate the velocity changes but the speed doesn't
3 ways to accelerate?
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).
How is the velocity of a car different from its speed?
The velocity of a car includes both its speed and its direction of motion, while speed is simply the magnitude of the velocity without considering direction. Velocity is a vector quantity, meaning it has both magnitude and direction, whereas speed is a scalar quantity, only representing the magnitude of motion.
What makes velocity different from speed?
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
