WHEN A SOCCER PLAYER KICKS A BALL, THE BALL ACCELRATES. EXPLAIN WHAT CAUSES THIS ACCELERATION IN TERMS OF FORCES? EXPLAIN WHAT HAS A GREATER INERTIA- A SPEEDING CAR OR A JET AIRPLANE SITTING ON A RUNWAY.

DO FORCES ALWAYS CAUSE MOTION? EXPLAIN

DESCRIBE THREE EXAMPLES FROM SPORTS IN WHICH A FORCE CHANGES HE VELOCITY OF AN OBJECT OR A PERSON.

When we kick the ball, the force we apply to it causes it to accelerate from a speed of 0 to a speed of dozens of kilometers per hour. When the ball is released from the foot, it begins to decelerate (negative acceleration) due to the force of friction that is exerted upon it (as we observed in the previous example).

Explanation:

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.  

yes the answer is total mass in unchanged   : )
