T or F: According to Newtonโs 3rd law of motion, in a car crash, if one car has more mass than the other, the amount of force that the smaller car exerts on the larger car is EQUAL TO what the larger car exerts on the smaller car.
True, Newton's Third Law is not affected by mass, but it's likely that the smaller car will have more damage.
