force is a quantity made up of?weight and speed?time and acceleration?magnitude and direction?mass and velocity?
Force is a physical quantity that is made up of both magnitude and direction. In other words, it has both size and a specific direction in which it acts. The correct combination is mass and acceleration.
To understand this concept, we can refer to Newton's second law of motion, which states that the force acting on an object is directly proportional to its mass and acceleration. The equation representing this relationship is F = m * a, where F is the force, m is the mass, and a is the acceleration.
So, if you want to calculate the force acting on an object, you need to know both its mass and the acceleration it experiences. By multiplying these two values together, you can determine the magnitude of the force. Additionally, the direction of the force is usually indicated by an arrow or specified in the problem context.
Therefore, the correct combination to describe a force is mass and acceleration, as force is directly dependent on these two factors.
