Is force a scalar quantity? Scalar quantities aredefined by a magnitude with no applicable direction. ... Some common scalar quantities are distance, speed, mass, and time. Some common vector quantities are force, velocity, displacement, and acceleration. ...
英语中的speed和velocity,哪个是速度哪个是速率?今天翻看英文的物理课本,发现一个问题,书里提到speed is a scalar quantity(标量),velocity is a vector quantity(矢量),但speed是速度,velocity是速率,这和高中物理书上所说的速度属于矢量,速率属于标量不是相反吗?望高人指点....

A force is avector quantity. A vector quantity is a quantity which has both magnitude and direction. To fully describe the force acting upon an object, you must describe both its magnitude and direction. Thus, 10 Newtons of force is not a complete description of the force acting on an obj...
