Nancy asks…some motion (physics) questions?1.why is it that an object can accelerate while traveling a constant speed, but not at constant velocity?
2.which has the greater acceleration when moving in a straight line-a car that increases its speed rom 50 to 60 km/h, or a bicycle that goes from zero to 10kim/h in the same time? Defend your answer.
3. a)If a freely-falling rock were equipped with a speedometer, by how much would its speed readings increase with each second of fall?
b)suppose
