(4) Science concepts. The student knows concepts of force and motion evident in everyday life. The student is expected to:
- (A) describe and calculate an object's motion in terms of position, displacement, speed, and acceleration;
- (B) measure and graph distance and speed as a function of time ;
- (C) investigate how an object's motion changes only when a net force is applied, including activities and equipment such as toy cars, vehicle restraints, sports activities, and classroom objects;
- (D) describe and calculate the relationship between force, mass, and acceleration using equipment such as dynamic carts, moving toys, vehicles, and falling objects;
- (E) explain the concept of conservation of momentum using action and reaction forces ;
- (F) describe the gravitational attraction between objects of different masses at different distances ; and
- (G) examine electrical force as a universal force between any two charged objects .
