Actually, a car always accelerates on a curve. This is because acceleration, like the velocity it alters, is a vector that has both magnitude and direction. Since taking a curve involves a change of direction, there must be an acceleration to alter the direction; otherwise, the car can only continue straight.
No, even if a car is moving at a constant speed while rounding a corner, it is still undergoing centripetal acceleration towards the center of the curve. This acceleration is responsible for changing the direction of the car's velocity.
If the car is going at a constant speed of 100 km/h, then its acceleration is zero. Acceleration measures the rate of change of velocity, and since the car's speed is not increasing or decreasing, there is no acceleration.
The acceleration of the car is equal to the rate of change of its speed over time. When a car goes from zero speed to a higher speed, it experiences positive acceleration in the direction of its motion.
The acceleration of a car at a steady speed of 50 mph is zero. Acceleration is the change in velocity over time, so when the car is maintaining a constant speed, there is no change in velocity and therefore no acceleration.
The acceleration of a car traveling at a steady speed of 60 mph is zero. Acceleration refers to a change in velocity over time, so a steady speed means there is no change in velocity and therefore no acceleration.
No, even if a car is moving at a constant speed while rounding a corner, it is still undergoing centripetal acceleration towards the center of the curve. This acceleration is responsible for changing the direction of the car's velocity.
Its speed is 55 mph, and if the highway doesn't curve, then its acceleration is zero.
Yes and No. No in the sense that the speed is not changing. What you are feeling is the change in direction as the car rounds the turn, an effect called centripetal acceleration.
Zero.
If the car is going at a constant speed of 100 km/h, then its acceleration is zero. Acceleration measures the rate of change of velocity, and since the car's speed is not increasing or decreasing, there is no acceleration.
The acceleration of the car is equal to the rate of change of its speed over time. When a car goes from zero speed to a higher speed, it experiences positive acceleration in the direction of its motion.
If the speed is constant, the acceleration is toward the center of the circle.
If the vehicle is gaining speed on that gentle curve, yes. Otherwise, no.
The acceleration of a car at a steady speed of 50 mph is zero. Acceleration is the change in velocity over time, so when the car is maintaining a constant speed, there is no change in velocity and therefore no acceleration.
The acceleration of a car traveling at a steady speed of 60 mph is zero. Acceleration refers to a change in velocity over time, so a steady speed means there is no change in velocity and therefore no acceleration.
No, If a car moves around a circular race track with any constant speed, the acceleration is directed towards the centre. So it has a centripetal acceleration. The tangential acceleration would be irrelevant unless the car has an instantaneous tangential velocity of zero. Then the centripetal acceleration is zero. However, this would only exist for that small instant in time.
One example of centripetal acceleration is when a car goes around a curve on a road. The car accelerates towards the center of the curve due to the centripetal force required to keep it moving in a curved path.
