Are they the same thing?
momentum = p = mv
momentum = p = mv
"momentum is the measure of inertia "
student85 said:Virtual said momentum is the measure of inertia. [That] makes sense since the faster the object is going, the harder it is to change its condition...
Virtual was wrong to say that because...student85 said:Virtual said momentum is the measure of inertia.
No, you are clearly not right as f=ma doesn't say anything about velocity, does it? If it got harder to change velocity when speed was higher, those terms should appear in that equation.Then, velocity must be part of inertia. I think it makes sense since the faster the object is going, the harder it is to change its condition...am I right?
Inertia is the tendency of an object to resist changes in its motion. It is the property of matter that causes it to maintain its state of rest or uniform motion in a straight line unless acted upon by an external force.
Momentum is the quantity of motion possessed by a moving object. It is the product of an object's mass and velocity, and is a measure of how difficult it is to stop or change the motion of an object.
Inertia and momentum are related in that they both involve the resistance to changes in motion. An object with a greater mass has a greater inertia and therefore requires more force to change its motion, and also has a greater momentum due to its mass and velocity.
The main difference between inertia and momentum is that inertia is a property of matter that describes its resistance to changes in motion, while momentum is a measure of an object's motion. Inertia is a property of an object, while momentum is a quantity associated with an object's motion.
Momentum is a vector quantity because it has both magnitude and direction. The direction of an object's momentum is the same as its velocity, and the magnitude of its momentum is determined by its mass and velocity. This makes momentum a vector quantity, as it has both magnitude and direction.
