Consider the video demonstration that you just watched. A more complete explanation of what you saw will be possible after covering Newton's laws. For now, consider the following question: How would the result of this experiment change if we replaced the ball with another one that had half the mass

The second law is given by

F = m a

Explanation:

Newton's second law is the real law.

It shows that the force acting on the object is directly proportional to the rate of change of momentum of the body.

F = m (v - u) / t

F = m a

where, m is the mass of the body, a is the acceleration, v is the final velocity and u is the initial velocity.

If the mass is halved and to keep the force same the acceleration is doubled.

this is poiselle's equation from fluid mechanic in physics. mech eng

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
