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?
A) A body in motion stays in motion at the same speed.
B) 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.
D) A body in motion tends to continue in a straight line and requires a force to turn.

Respuesta :

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

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

Explanation :

We know that race car drivers must slow down as they take turns on the track.

According to Newton's first law, an object will remain at rest and in motion until an unbalanced external force is applied to it. This law also called the law of inertia.

Inertia is the property of an object that opposes its state of rest or state of motion.

The race car driver will try to continue in a straight motion. But as they reach the turns he bends due to inertia.

So, the correct option is (D)  "A body in motion tends to continue in a straight line and requires a force to turn".
