Answer to Question #262995 in Physics for Tracy queenie

Question

Situation C: Two students are sitting on a swing. Student A is 40 kilograms while student B is 50 kilograms.

1) Who will swing with greater acceleration: student A or student B? Justify your answer.

2) What physical quantity was changed in this situation?

3) What relationship exists between the varying physical quantity and acceleration?

4) Combining the ideas from the three situations, how do state the law of acceleration?

Answer 1

1) Student A

$$40a_1=50a_2$$

2) Mass

3)

$$F=ma$$

4) Newton's second law of motion states that the acceleration of a system is directly proportional to and in the same direction as the net external force acting on the system, and inversely proportional to its mass.
