Explanation

Momentum is the product of an object’s mass and its velocity → Momentum = Mass × Velocity.

Momentum is given by the formula: p = mv

It is a vector quantity.

It is conserved in closed systems during collisions.

It depends on mass and speed, not on acceleration, so momentum is independent of acceleration.

Explanation

The value of log 1, regardless of the base (as long as it's a valid base for logarithms,i.e., positive and not equal to 1), is always 0.

This is because any number raised to the power of 0 equals 1.

For example, log₁₀(1) = 0 and ln(1) = 0. 

Explanation

A derived quantity is obtained from fundamental quantities (like mass, length, and time).

Force = Mass × Acceleration (Newton’s Second Law), so it is derived from mass, length, and time.
