What Forces Act on a Car Pushing a Block in Physics?

Click For Summary

Homework Help Overview

The discussion revolves around the forces acting on a car that is pushing a block across a surface. Participants are tasked with drawing a free body diagram that includes various forces such as the force exerted by the block on the car, friction, gravity, and the normal force.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants discuss the components of the free body diagram, including the normal force and gravitational force. There is a question about the interpretation of forces, particularly regarding action-reaction pairs and how they relate to the movement of the car.

Discussion Status

The discussion is ongoing, with participants exploring different interpretations of forces and their relationships. Some guidance has been offered regarding the labeling of forces, and questions about the dynamics of the system are being raised.

Contextual Notes

There is some confusion regarding the terminology used, such as the mention of a "rabbit" instead of a block, which may indicate a misunderstanding or a playful remark. Participants are encouraged to focus on the object as a system without delving into unnecessary details.

Homework Statement


A car pushes a block across the floor. (assume that it is moving from left to the right)

Draw a free body diagram for the car showing: Force by block on car. Force of friction. Force of Gravity. Normal force.

Homework Equations


The Attempt at a Solution



Normal force Straight up, gravity straight down. Force of box on car going left + force of friction going left.

alright, i'll attach something for you

Note: Remember that no matter what your object is, it will remain as a box. Do not bother into details, only what that object (or system) it is.

is "force by rabbit" the same as force of car on rabbit? I interpreted that as the equal and opposite reaction push back onto the car from the rabbit.
 
they are action-reaction pairs I think, but no, they are separate forces. Remember to label each one with a different name.

when did the block change into a rabbit?
Normal force Straight up, gravity straight down. Force of box on car going left + force of friction going left.
if the friction force on car and force of block on car both point left, how does the car move to the right?
