  1. › wiki › VelocityVelocity - Wikipedia

    Velocity is a physical vector quantity; both magnitude and direction are needed to define it. The scalar absolute value of velocity is called speed, being a coherent derived unit whose quantity is measured in the SI (metric system) as metres per second (m/s or m⋅s −1). For example, "5 metres per second" is a scalar, whereas "5 metres per ...

  2. Consider a 0.5-kg physics cart loaded with one 0.5-kg brick and moving with a speed of 2.0 m/s. The total mass of loaded cart is 1.0 kg and its momentum is 2.0 kg•m/s. If the cart was instead loaded with three 0.5-kg bricks, then the total mass of the loaded cart would be 2.0 kg and its momentum would be 4.0 kg•m/s. A doubling of the mass ...

  3. Speed is measured as the ratio between the distance and time and the SI unit of speed is m/s. It is the change in the position of an object with respect to time. There are four types of speed: uniform speed, variable speed, average speed, and instantaneous speed.

  7. In relation to the movement, we can correlate magnitude with the size and speed of the object while travelling. The size of the object or the amount is its magnitude. Like in case of speed, a car is travelling faster than a motorbike. In this case, the magnitude of the speed of the car is more than that of motorbike.
