Linear momentum is a measure of an object's motion in a straight line, while angular momentum is a measure of an object's rotational motion around an axis.
Linear momentum is calculated by multiplying an object's mass by its velocity in the direction of motion. The formula is p = mv, where p is momentum, m is mass, and v is velocity.
An object's linear momentum can be affected by its mass, velocity, and external forces acting upon it. The greater the mass or velocity of an object, the greater its linear momentum will be. External forces, such as friction or gravity, can also change an object's momentum.
Angular momentum is conserved when the net external torque acting on a system is zero. This means that the total amount of angular momentum in a system will remain constant unless acted upon by an external force.
Yes, an object can have both linear and angular momentum at the same time. For example, a spinning top has both rotational motion (angular momentum) and linear motion (linear momentum).
