... Weight is the force of gravity acting on a body. An object is truly weightless only if there is no other body around to exert a gravitational force on it. Force of air resistance acting toward the rear of the car and a force of static friction between the car’s roof and the book acting forward. Stat ...

... What about this? Would you believe that this ball and this marble would fall at the same rate if I dropped them together? And what would that rate be on earth? If you said that they both would accelerate at 9.8 m/s2, you’re right. Let’s see why. Many students, especially the surfer types, will say t ...

... Newton’s 1st law states that in the absence of force, a body continues moving in a straight line at constant velocity. Already, this means that only B and E could possibly be correct - once the ball leaves the tube, there are no forces acting on it, so it must move in a straight line. So, basically ...

The forces of gravity accelerating the skydiver towards earth are matched exactly by the force of friction from the air particles pushing against the skydiver. If the person wears a more aerodynamic suit or points their ...
