What is the meaning of "free", as used in physics in the expression "free fall"? Free fall means free of In everyday language, "free falling" describes objects that move directly towards the ground. Is that necessarily the case in physics that a free-falling object must be moving directly towards the ground? Describe or name the three ways to accelerate, in the physics sense of the term. Fill in the blank: Galileo discovered t that the horizontal component of the velocity of free-falling objects on earth is Fill in the blank: Galileo discovered that the vertical component of the velocity of free-falling objects on earth is

Explanation / Answer

2) free fall means falling under the force of gravity only

3) no, an upward moving object can also be free falling

4) three ways to accelerate are

a) speed up

b) speed down

c) object can change direction

5) constant (as no acceleration acts in the horizontal direction)

6) increases if particle is going up and decreases if it comes down
