Mechanics Laws of Motion: Three statements that make powerful predictions by Thomas Pasquini, Ph.D. Reading Quiz Teach with this A force is a ___________ quantity, which includes both magnitude and direction. scalar vector mathematical constant Acceleration and force are directly proportional to one another. This means that ____________. as the force on an object increases, the acceleration of the object will also increase. the force and acceleration of an object are always the same. as the force on an object increases, the acceleration of the object does not change. as the force on an object increases, the acceleration of the object decreases. The laws of motion have been superceded by modern physics and are no longer relevant. true false Which of the following statements most accurately describes the development of the laws of motion? Newton developed the laws by conducting experiments. Other scientists developed the laws and Newton published them. Newton watched a soccer game to get ideas about motion. Newton compiled and built on the work of many other scientists. When a baseball player hits a ball with a bat, which of the following would be likely to create a greater acceleration of the ball? Increasing the force by using a heavier bat Increasing the mass of the ball by soaking it in water Decreasing the force by using a lighter bat Increasing air resistance by using a ball with a rougher surface Score Quiz
