a. An object that is free-falling is acted upon by the force of gravity alone. b. A falling skydiver which has reached terminal velocity is considered to be in a state offree fall. c. A ball is thrown upwards and is rising towards its peak. As it rises upwards, it is NOT considered to be in a state offree fall d. An object in free fall experiences an acceleration which is independent of the mass of the object. e. A ball is thrown upwards, rises to its peak and eventually falls back to the original height. As the ball rises, its acceleration is upwards; as it falls, its acceleration is downwards. f. A ball is thrown upwards, rises to its peak and eventually falls back to the original height. The speed at which it is launched equals the speed at which it lands. (Assume negligible air resistance.) g. A very massive object will free fall at the same rate of acceleration as a less massive object.
According to Newton’s second law: a. The velocity of a particle is equal to the net force on the particle divided by the mass of the particle. b. The net force on a particle is equal to the product of the velocity of the particle with the acceleration of a particle. c. The net force on a particle is equal to the product of the mass of the particle with the acceleration of a particle. d. The velocity of a particle is equal to the net force on the particle multiplied by the mass of the particle.
