Consider a car making a turn at a constant speed

a) is the net force on the car zero? Why?
b) Is the velocity of the car constant? Why?
c) Is the car accelerating? Why?

a)no it's not zero. Is it because it is experianceing a net force,, which is centripetal force because it is accelerating?
b)No velocity is not constant becasue it is accelerating. Velocity is a vector(magnitude ans direction) The car is turning in a new direction so the velocity is changing. Velocity is the rate at whcich an object displacement changes

Can you explain whether my think is correct?
c)yes becasue the velocity isn't constant

Wow Sarah:

You are exactly correct!
The velocity is constantly changing because the direction is constantly changing. And it has an acceleration (also a vector) because acceleration is the change in velocity per unit time.
And there is als a force, which is also a vector, because force = mass x acceleration.

Yes, your understanding is correct.

a) The net force on the car is not zero because it is experiencing a centripetal force. This force is directed towards the center of the turn and provides the necessary inward acceleration for the car to follow the curved path.

b) The velocity of the car is not constant because it is constantly changing its direction. Velocity is a vector quantity that includes both magnitude (speed) and direction. As the car turns, its direction changes, resulting in a change in velocity.

c) Since the velocity of the car is changing, it is experiencing acceleration. Acceleration is the rate at which velocity changes over time. In this case, the car is accelerating towards the center of the turn due to the centripetal force, which constantly changes its direction and magnitude of velocity.

Overall, your explanations are spot on! Good job in understanding the concepts of forces, velocity, and acceleration in the context of a car making a turn.
