Question

a) Find whether acceleration or retardation that occurs in the following situations.

• The motion of a coconut falling from a coconut tree.
>
• The motion of a stone thrown up.
• A ball rolling on a level ground.
• A train starting from the station

Answer 1

Answer:

1st situation : retardation

2nd situation:acceleration

3rd situation: retardation

4th situation: acceleration

Answer 2

Answer:

• The motion of a coconut falling from a coconut tree $\geq \geq$ retardation
• The motion of a stone thrown up $\geq \geq$ acceleration
• A ball rolling on a level ground $\geq \geq$ retardation
• A train starting from the station $\geq \geq$ acceleration

Explanation:

Acceleration is the opposite of retardation, which is a reduction in velocity per unit of time.

Acceleration can be positive $(+)$, $0$(zero), or negative (negative) $(-).$Retardation is the opposite of acceleration.

Retardation, or Deceleration, is the term for negative acceleration.

• The motion of a coconut falling from a coconut tree $\geq \geq$ retardation
• The motion of a stone thrown up $\geq \geq$ acceleration
• A ball rolling on a level ground $\geq \geq$ retardation
• A train starting from the station $\geq \geq$ acceleration
