What is Photosynthesis? Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. This process occurs in plants and some algae (Kingdom Protista). Plants need only light energy, CO2, and H2O to make sugar. The process of photosynthesis takes place in the chloroplasts, specifically using chlorophyll, the green pigment involved in photosynthesis. Plants, animals and humans are very similar in this because all of us need Photosynthesis is to live, we need the energy of the sun to live. Respiration is the process of where cells

Motion of a Dynamics Cart That Occur When Different Amounts of Net Force Are Applied on a System with Constant Mass
Objective: In this laboratory activity, we will investigate the changes in the motion of a dynamics cart that occur when different amounts of net force are applied on a system with constant mass. And we will also investigate the changes in motion that occur when the applied force is constant, but the total mass of the system is changed. Theory: Newton's Second Law of Motion states that when a force acts on an object, it will cause the object to accelerate. The larger the mass of the object, the greater the force will need to
