Race car drivers must slow down as they make turns on the track. This is best explained by the law of inertia. Which statement best describes inertia for the car going around a turn?

Question

A A body in motion stays in motion at the same speed.A body in motion stays in motion at the same speed.
B The speed of the car going into the turn must be conserved.The speed of the car going into the turn must be conserved.
C The speed around a turn is proportional to the radius of curvature of the turn.The speed around a turn is proportional to the radius of curvature of the turn.
D A body in motion tends to continue in a straight line and requires a force to turn.

Answer 1

The statement that best describes inertia for the car going around a turn is:

D: A body in motion tends to continue in a straight line and requires a force to turn.

This aligns with the law of inertia, which states that an object in motion will continue to move in a straight line unless acted upon by an external force. When a car makes a turn, it must exert a force (through friction and steering) to change its direction, overcoming its tendency to continue in a straight line.
