1.2 What are forces? Forces have a similar aspect to air, it is all around you but you can still not visibly see it. The definition for force is strength or energy as an attribute of physical action or movement (Wikipedia, 2015). An example of force is a football is kicked harder. It moves faster later after some time its force decreases due to friction. 1.3 What is Mass and Weight? Mass is the amount of matter present in a body while weight is a measure of how strongly gravity pulls on that matter. Mass is an intrinsic property of the body and remains the same wherever the body might be. Weight is a force, and force is (Mass x Acceleration). The weight of an object is its mass times the acceleration due to gravity. The weight of the body differs by place. For example, objects weigh less on the moon where gravity is lower compared to the Earth. 1.4 What are Newtons Laws of Motion? Sir Isaac Newton created three laws of motion the first one is sometimes referred to as the law of inertia. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force (Peters, 2011). Sir Isaac Newton’s second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object
