What else can I help you with?
How would you describe your motion in terms of velocity and acceleration as you ride in a car down the street come to a red light wait for the green light and then start off again?
As the car moves down the street, the velocity is positive. As it comes to a red light and stops, the velocity decreases to zero. Waiting at the red light, the acceleration is zero. When the light turns green and the car accelerates, the velocity increases from zero to a positive value, and the acceleration is positive.
what is the velocity of 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 acceleration example occurs when a car stops at a traffic light?
Rather, a car stoppping at a light is an example of deceleration but one of the possible example of acceleration when a car stops at a traffic light is a pedestrian accelerating across the road or other car in different lanes accelerating to move to on in their journey.
What is the velocity of light in meters?
the velocity of light is 300000000 m/s
What is an example of positive velocity and positive acceleration?
A car in the middle of the intersection, 3 seconds after the light turned green.
Explain the circumstances when the acceleration and the velocity of car are parallel?
when velocity of a car is increasing then velocity and acceleration are parallel to each other.
Speed of light in car then turned on the headlight?
The speed of light is constant in a vacuum at approximately 299,792 kilometers per second. When a car turns on its headlights, the light produced also travels at this speed, regardless of the car's own velocity.
What happens when you decrease the velocity of a car?
as you decrease the velocity of a car, you decrease the kinetic energy.
Is the velocity constant if a car is going around a curve?
No, the velocity of a car is not constant when it is going around a curve. The direction of the car's velocity is changing as it navigates the curve, even if its speed remains the same, so the velocity is not constant.
A car travels 180 miles west in 3 hours what is the velocity of the car?
The velocity of the car is 32 mph
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.
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.
