• Recall Newton's Laws of motion.
• Describe Newton's second law of motion as rate of change of momentum.
• Define impulse as a product of impulsive force and time.
• Describe the law of conservation of momentum.
• Use the law of conservation of momentum in simple applications including elastic between two bodies in one dimension.
• Describe the force produced due to flow of water.
• Understand the process of rocket propulsion (simple treatment).
• Understand projectile motion in a non-resistive medium.
• Derive time of flight, maximum height and horizontal range of projectile motion.
