Which one of the following statements is not true? the equations of kinematics apply to free-fall motion. near the earth's surface the acceleration due to gravity has the approximate magnitude of 9.80 m/s2, points downward when the motion is downward, and points upward when the motion is upward. in the absence of air resistance the motion of a baseball dropped from rest from the top of a building is an example of free-fall. in the absence of air resistance the motion of a baseball after being thrown straight upward from the ground is an example of free-fall. in free-fall motion near the earth's surface the acceleration is the acceleration due to gravity.

Explanation:

1) The equations of kinematics apply to free-fall motion.

TRUE

we can apply kinematics in all such situations where acceleration is constant

2) Near the earth's surface the acceleration due to gravity has the approximate magnitude of 9.80 m/s2, points downward when the motion is downward, and points upward when the motion is upward.

FALSE

Acceleration due to gravity always in downwards direction

3) In the absence of air resistance the motion of a baseball dropped from rest from the top of a building is an example of free-fall.

TRUE

When only gravitational force is acting on a system then it is an example of free fall

4). In the absence of air resistance the motion of a baseball after being thrown straight upward from the ground is an example of free-fall.

TRUE

When only gravitational force is acting on a system then it is an example of free fall

5). In free-fall motion near the earth's surface the acceleration is the acceleration due to gravity.

TRUE

In free fall the net force on the ball is due to gravity only so the acceleration is only due to gravity

step-by-step explanation:

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
