错mass*acceleration （加速度）= force
力移动物体所需取决于其质量和加速度。选项 A“speed”指速度,侧重于运动的快慢。选项 C“velocity”也表示速度,但更强调速度的方向和大小。选项 D“direction”指方向,不符合力的影响因素。而“acceleration”加速度是力影响物体运动状态的重要因素之一。

Newton’s laws of motion - Force, Mass, Acceleration: Newton’s second law is a quantitative description of the changes that a force can produce on the motion of a body. It states that the time rate of change of the momentum of a body is equal in both ma

Newton’s Second Law of Motion states, “The force acting on an object is equal to the mass of that object times its acceleration.”
Subsequently, stepwise regression was used to produce two 30m sprint time prediction models from TM performance (TM1: body mass+TM-data; and TM2: body composition+TM-data) in a validation group (n=39) and then cross-validated against another group (n=39). As no significant differences were...
