If a car is moving at 90 km/h and it rounds a corner, also at 90 km/h, does it maintain a constant speed? A constant velocity? Defend your answer.

Solution 9RQ Introduction Speed and velocity are different quantities in Physics. Speed is having only magnitude but velocity is having both magnitude and direction. So, speed is a scalar quantity and velocity is a vector quantity. Step 1 Consider, figure 1 is the representation of a car which rounds a corner. If the car is moving with 90 km/hr before it rounds the corner and it keeps moving at 90km/hr after taking the curve, then the speed is said to be a constant since there is no change for the magnitude. In the diagram,...
