Calculate the acceleration of an object, given the object’s mass and the net force on the object, using Newton’s Second Law of Motion (F=ma).
Force and Motion
In prior grades students learned to measure, record, and calculate the average speed of objects, and to tabulate and graph the results. In grades 9-11 students learn to apply Newton’s Laws of Motion and Gravity both conceptually and quantitatively. Students are able to calculate average speed, velocity, and acceleration. Students also develop an understanding of forces due to gravitational and electrical attraction. These fundamental concepts enable students to understand the forces that govern the observable world and provide a foundation for a full course in physics.
A net force will cause an object to accelerate or change direction. A less massive object will speed up more quickly than a more massive object subjected to the same force (Newton’s Second Law of Motion, F=ma).
