The velocity of the car must be constant. Strange as it may seem, it is just as hard to push a car on the Moon as it is to push the same car on Earth. This is because a. the mass of the car is independent of gravity. A car is much more easily pushed on the Moon than on the Earth. Scalar quantities have magnitude only.
Speed is a scalar quantity.
A race car travels northward on a straight, level track at a constant speed, traveling 0.850 km in 20.0 s. The return trip over the same track is made in 25.0 s. Force and Newton's Laws of Motion 1. An unbalanced force always produces a. a uniformly changing inertia. The unit of force in the mks system is the a. Newton .
