Standard Science Primary 6 Interactions

Two identical balls, A and B, were dropped from different heights. Ball A was dropped from 2 metres while Ball B was dropped from 5 metres. Which of the following is true about the gravitational force acting on the balls?

A The gravitational force on Ball B is greater because it is higher.
B The gravitational force on both balls is the same because they have the same mass.
C The gravitational force on Ball A is greater because it is closer to the ground.
D There is no gravitational force acting on the balls before they are dropped.

Worked Solution

Step 1: Gravitational force (weight) depends on the mass of the object and the strength of the gravity. Step 2: Since both balls are identical, they have the same mass. Step 3: Therefore, the Earth pulls both balls with the same gravitational force.

Correct answer: The gravitational force on both balls is the same because they have the same mass.
