... The above condition is sufficient for a point-like object to be at its translational equilibrium. However for an object with size this is not sufficient. One more condition is needed. What is it? Let’s consider two forces equal in magnitude but in opposite direction acting on a rigid object as shown ...

Centripetal Force
... In this experiment we will measure the force required to keep a mass moving at constant angular velocity in a circle of constant radius. This force will be applied by a spring suspended between the mass and a post at the center of the circle about which the mass rotates. The general outline of the a ...

Linear momentum / Collisions
... If the component of the net external force on a closed system is zero along an axis component of the linear momentum along that axis cannot change. The momentum is constant if no external forces act on a closed particle system. Internal forces can change the linear momentum of portions of the syst ...

Example Problem - Resolving a Velocity Vector into Its Components
... using vectors. We can use the techniques for adding and resolving vectors to analyze the acceleration of objects that have several forces exerted on them. Equilibrium When the net force-the net sum of all the forces acting-is zero, the object is in equilibrium. According to Newton's laws, the object ...

... We have an idea of what mass is from everyday life. In physics: Mass (in Phys 207) is a quantity that specifies how much inertia an object has (i.e. a scalar that relates force to acceleration) (Newton’s Second Law) Mass is an inherent property of an object. Mass and weight are different qua ...
