Which best contrasts newton’s and einstein’s ideas?

newton believed that mass tells objects how to move. einstein believed that the curvature of space-time tells force how to move objects.
newton believed that force tells mass how to move. einstein believed that the curvature of space-time tells velocity how to change.
newton believed that distance tells gravity how much force to exert. einstein believed that distance tells space-time how to curve.
newton believed that mass tells gravity how much force to exert. einstein believed that mass tells space-time how to curve.

Iknow the first part it is the average star i am not 100% sure

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
