Description: A car pulls a trailer down the highway. Let Ft be the magnitude of the force on the trailer due to the car, and let Fc be the magnitude of the force on the car due to the trailer. If the car and trailer are moving at a constant velocity across level ground, then Ft=Fc. If the car and trailer are accelerating up a hill, what is the relationship between the two forces?

Question

A car pulls a trailer down the highway. Let $F_{\mathrm{t}}$ be the magnitude of the force on the trailer due to the car, and let $F_{c}$ be the magnitude of the force on the car due to the trailer. If the car and trailer are moving at a constant velocity across level ground, then $F_{t}=F_{c}$. If the car and trailer are accelerating up a hill, what is the relationship between the two forces?

Step 1

In this case, the net force acting on the system is zero. This is because the force exerted by the car on the trailer, $F_{t}$, is equal and opposite to the force exerted by the trailer on the car, $F_{c}$. Therefore, we can write this as: \[F_{t} = F_{c}\] Show more…

Key Concepts

Newton's Third Law

Newton's Third Law states that whenever two bodies interact, they exert forces on each other that are equal in magnitude and opposite in direction. This law holds regardless of the state of motion of the objects involved, whether they are moving at a constant velocity or accelerating, ensuring that action-reaction force pairs remain equal.

Dynamics of Accelerating Systems

In an accelerating system, such as a car and trailer going uphill, additional forces such as those due to gravity and the need for net force to produce acceleration come into play. However, while the overall net forces on each body may differ as they overcome these external influences, the mutual interaction forces between the car and trailer remain equal in magnitude due to the inherent symmetry enforced by Newton's Third Law.
