As a result, an increasing speed leads to an increasing momentum – a direct relationship. As the speed of an object increases, so does its velocity. ![]() TRUE – Momentum is calculated as the product of mass and velocity. Negative quantities move backwards or down, whereas positive quantities typically indicate the object is moving forward or up. In physics, direction is indicated by the sign, positive or negative. ![]() Momentum is a vector quantity, meaning it has both magnitude and direction. Alternatively, the centimeter per second (cm/s) can be used to express velocity magnitude. The standard unit of velocity magnitude (also known as speed ) is the meter per second (m/s). Velocity is a vector expression of the displacement that an object or particle undergoes with respect to time. The force acting on a body for short interval of time is called impulsive force. The product of the force
