what is the physical relationship between mass and speed?

Mass doesn't affect speed directly. It determines how quickly an object can change speed (accelerate) under the action of a given force. Lighter objects need less time to change speed by a given amount under a given force.

The larger the mass of a moving object, the less readily it moves. According to Newton's second law of motion, the acceleration that the object experiences is inversely proportional to its mass, and you can calculate this acceleration from the object's change in speed over a set amount of time.

Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.

They are very different quantities. Velocity is the speed in a certain direction, e.g. 100mph north would be a velocity. Mass is easiest understood as a measure of how hard it is to change that objects velocity*. ... Mass is different from weight, which is mass times the strength of gravity.

Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. Speed is ignorant of direction. On the other hand, velocity is a vector quantity; it is direction-aware.

Mass is the amount of matter in an object and is expressed in kilograms. Acceleration is the rate of change of velocity of an object in the same straight line of the unbalanced force. ... Thus, an object of constant mass accelerates in proportion to the force applied.

A: Newton's second law of motion describes the relationship between an object's mass and the amount of force needed to accelerate it. Newton's second law is often stated as F=ma, which means the force (F) acting on an object is equal to the mass (m) of an object times its acceleration (a).

Speed is the rate of motion, or the rate of change of position. It is expressed as distance moved (d) per unit of time(t). Speed is a scalar quantity with dimensions distance/time. Speed is measured in the same physical units of measurement as velocity, but does not contain an element of direction.

There is a huge difference between speed and momentum. Speed tells us how much distance an object has covered in a given amount of time. ... Momentum = Mass*Velocity. Speed has no direction specified with it whereas momentum has a direction defined on the basis of the objects velocity.

The faster an object moves, the more kinetic energy it has. The more mass an object has, the more kinetic energy it has.

Momentum is mass times velocity. So force is the change in (mass times velocity) with respect to time: F = d(mv)/dt. In most situations we figure mass is constant. So force is proportional to a change in velocity.

They are both related to an object's velocity (or speed) and mass, but momentum is a vector quantity that describes the amount of mass in motion. Kinetic energy is a measure of an object's energy from motion, and is a scalar. Sometimes people think momentum is the same as force.

The mass amount does not change the formula because all objects accelerate at the same rate when falling downward. Take the final velocity/speed amount, or 0.99 meters per second, and plug it into the basic formula for speed: speed = distance/time.

Mass is the amount of matter in an object and is expressed in kilograms. Acceleration is the rate of change of velocity of an object in the same straight line of the unbalanced force. ... Force (N) = mass (kg) × acceleration (m/s²). Thus, an object of constant mass accelerates in proportion to the force applied.

There is, in fact, a relationship between speed and time. S= d/t, where S is speed, d is distance, and t is time. So speed is dependent on time, as in the speed is determined by the distance divided by the time.

The speed is the time rate of change of the distance. If 'D' is the distance of an object in some time 'T', the speed is equal to, s = D/T. It has the same units as velocity. let us solve some examples, we will introduce the formulae as we go along.

Mass is a measure of the amount of matter in an object. Inertia is the resistance of a physical object to any change in its state of motion.
