WebFriction is dependent on the smoothness or roughness of the two surfaces that are in contact with each other. When the surface is smooth, the friction between the two reduces as there is not much interlocking of … WebIt is saying that the force due to gravity is a standard gravitation constant g times the mass of the object m, or. F = gm. In beginners' Physics we all learn (ed) the relationship amoung force F, mass m and acceleration a as being. F = ma. substituting for F we get a … WebThe car cannot be stationary, as the drag forces (air resistance/friction) only occur when an object is moving. Since the forces shown are due to the force of the engine and air resistance then ... cheddar grove primary school admissions
