- Physics student Matt has just learned about Newton's 3rd law of motion. He's considering a car pulling a trailer as shown below. T He thinks that since the tension force forward on the trailer is equal and opposite to the tension force backwards on the car, the net force on the car must be zero and therefore the car can't accelerate. Which one (or more) of the following statements is correct: The tension force forward on the trailer is not the same magnitude as the tension force backwards on the car. Matt has not considered all the forces acting on the car, such as the friction between the wheels and the ground, in order to calculate the net force on the car. The net force on the car is always zero and therefore the car cannot accelerate. Since the 2 tension forces act on different objects you can't add them together to get a “net force" on either object.A box of mass m is resting in the flat bed of a truck which is stopped at a red light on a road which slopes upward at an angle qabove the horizontal.
