a car is driving on the road. what is the correct relationship of forces acting between the earth and the car?
Answer
Explanation:
Step1: Identify forces
The Earth exerts a gravitational force (weight) on the car down - ward. The car exerts an equal and opposite normal force on the Earth. The only forces between the Earth and the car in the vertical direction are these two forces according to Newton's third law. There are no horizontal forces between the Earth and the car in terms of this interaction.
Step2: Analyze options
The correct relationship is the vertical up - down pair of forces. The first option has a horizontal force which is not part of the Earth - car interaction. The second option shows the gravitational force of the Earth on the car (downward) and the normal force of the car on the Earth (upward).
Answer:
The second option (the one with only vertical, opposite - directed forces)
