Movement Answers

Force is based upon both mass and acceleration.

What is the difference between velocity and acceleration?A.Velocity describes an object's position and acceleration describes how fast it moves.B.Velocity is how fast an object moves and acceleration is the rate of change in velocity.C.Velocity is used to determine the magnitude of force acting on an object, and acceleration isn't.D.Velocity is a time-dependent property of an object, while acceleration is not.

What distinguishes mass from weight?A.Mass is a measure of the amount of matter in an object, while weight is a measure of the force of gravity on the object.B.Weight is a measure of the amount of matter in an object, while mass is a measure of the force of gravity on the object.C.Mass is a measure of an object's inertial force, and weight is the force exerted by that object on other objects.D.Mass and weight are synonyms and ultimately describe the same principle.
