If a car is going 65mph makes a 90 degree, what changes?
most obviously, velocity
note that velocity includes speed and direction
Of course it would be Velocity but velocity is Distance
------------- + Direction
Speed
When a car is traveling at a certain speed and makes a 90-degree turn, there are several changes that occur. Here are a few key changes:
1. Change in Velocity: Velocity refers to the speed of an object in a specific direction. When a car makes a 90-degree turn, its velocity changes because the direction of its motion changes abruptly. The car's velocity will now have a component in the new direction of travel, resulting in a change in velocity.
2. Change in Centripetal Force: When a vehicle makes a turn, a centripetal force is required to keep it moving in a curved path. The centripetal force is directed towards the center of the curve and is responsible for changing the car's direction. The magnitude of the centripetal force depends on the mass of the car, its speed, and the radius of the turn.
3. Change in Acceleration: Acceleration is the rate at which an object's velocity changes. In this case, when the car makes a 90-degree turn, there is a change in acceleration. The car will experience a lateral acceleration towards the center of the turn, causing it to change its direction of motion.
4. Change in Friction: Friction plays a crucial role in the car's ability to make the turn safely. As the car turns, the tires interact with the road surface, and the friction between them provides the necessary force to change the car's direction. The friction force acting on the tires will increase or decrease depending on various factors such as tire grip, road conditions, and the weight distribution of the car.
It's important to note that making a sharp 90-degree turn at a high speed can be dangerous and may lead to loss of control or skidding. So, it's advisable to slow down before making such turns to ensure safety.
