Velocity is a measure of an object's speed and direction of motion, while force is a push or pull that causes an object to move, stop, or change direction. Velocity is a vector quantity and includes both speed and direction, while force is a vector quantity that causes acceleration in an object.

What is the difference between drag and velocity in the context of physics?
In physics, drag is a force that opposes the motion of an object through a fluid, like air or water. It acts in the opposite direction of the object's velocity. Velocity, on the other hand, is the speed of an object in a specific direction. So, the main difference is that drag is a force that hinders motion, while velocity is the speed and direction of that motion.
What is the difference between air resistance and velocity?
Air resistance is the force that opposes the motion of an object as it moves through the air. Velocity, on the other hand, is the speed and direction of an object's motion. Greater air resistance can slow down an object's velocity by exerting a force in the opposite direction.
What is the relationship between force, velocity, and momentum in physics, specifically when considering the equation p fv?
In physics, the relationship between force, velocity, and momentum is described by the equation p fv. This equation shows that momentum (p) is equal to the product of force (f) and velocity (v). Momentum is a measure of an object's motion, and it depends on both the force applied to it and its velocity. The greater the force or velocity, the greater the momentum of an object.
How power is dot product of force and velocity?
The dot product of force and velocity gives the power generated by the force on the object. It is calculated as the product of the magnitudes of force and velocity, multiplied by the cosine of the angle between them. This represents the rate at which work is done on the object by the force.
What is the difference between increasing velocity and uniform velocity?
Increasing velocity means that the body is accelerating and a force is acting on the body to produce the acceleration. Uniform velocity means that there is no acceleration or deceleration and so no force acts on the body. (Note that in practice we cannot achieve perpetual motion because of either the decelerating force of gravity or friction).

What is the difference between free fall and terminal velocity?
The difference between free fall and terminal velocity i that free fall is when an object is falling or descending through the air with little air resistance or drag. Terminal Velocity, on the other hand is when the resistance of air and the force of gravity balance each other out causing the object to reach a constant velocity. .
What is the relationship between centripetal force and velocity?
Centripetal force is = mass * velocity square divided by radius
What is mean velocity gradient?
The difference in velocity between adjacent layers of the fluid is known as a velocity gradient and is given by v/x, where v is the velocity difference and x is the distance between the layers. To keep one layer of fluid moving at a greater velocity than the adjacent layer, a force F is necessary, resulting in a shearing stress F/A, where A is the area of the surface in contact with the layer being moved.
What is the difference between air resistance and velocity?
Air resistance is the force that opposes the motion of an object as it moves through the air. Velocity, on the other hand, is the speed and direction of an object's motion. Greater air resistance can slow down an object's velocity by exerting a force in the opposite direction.
The distance between speed and velocity is that velocity includes?
Velocity includes direction. And it's the 'difference', not the 'distance'.
Is the greater an objects velocity the stronger the gravitational force on it?
No, the strength of the gravitational force on an object depends on the masses of the objects and the distance between them, not the object's velocity. The velocity affects the object's motion in the gravitational field, but not the strength of the gravitational force acting on it.

What is the relationship between force, mass, and velocity according to the equation fmv?
The relationship between force, mass, and velocity is described by the equation fmv. This equation states that the force acting on an object is equal to the product of its mass and velocity. In simpler terms, the force applied to an object depends on how heavy it is and how fast it is moving.
Does velocity affect frictional force?
No, velocity does not directly affect frictional force. Frictional force is primarily dependent on the nature of the surfaces in contact and the normal force acting between them. However, velocity can indirectly impact frictional force by generating heat due to more rapid motion, which can affect the coefficient of friction between the surfaces.
