**Pattern:** Problem based on the applications of Newton's Second Law

**Description**: The second law states that the force on an object is equal to its mass times its acceleration. Problems to determine the dynamics of motion of a system can be asked. While some questions are straightforward where second law equation can be directly applied, complex systems where we need to draw free body diagram to apply the second law equation are also asked often.

**Question that can be asked**

- To solve problem related to the motion of object under constant force.
- To calculate the velocities and acceleration of masses in a pulley-mass system.
- On the motion of objects on fixed or moving wedge.
- On the motion of objects under variable force.
