Smart book velocity and momentum answers?
Velocity: The velocity of an object is the rate at which it changes its position. It is a vector quantity, meaning that it has both a magnitude (speed) and a direction. The formula to calculate velocity is:
Velocity = Distance / Time
Momentum: Momentum is a measure of the motion of an object and is calculated by multiplying the mass of the object by its velocity. It is also a vector quantity, meaning that it has both a magnitude and a direction. The formula to calculate momentum is:
Momentum = Mass x Velocity
In conclusion, velocity and momentum are important concepts in physics that are used to describe the motion of objects. Velocity is the rate of change of an object's position, while momentum is the product of an object's mass and velocity.
