Solution:
1.
Mass is the amount of _______ contained in an object.
-
Answer: matter
-
Explanation: Mass is a measure of the amount of matter in an object. It remains constant regardless of location.
2.
Mass is measured in _______.
-
Answer: kilograms
-
Explanation: The standard unit for measuring mass is kilograms (kg).
3.
On the Earth, mass of an object is the _______ as its weight.
-
Answer: same
-
Explanation: On Earth, the mass and weight of an object are directly proportional, but they are not the same thing. However, the relationship is consistent under Earth's gravity.
4.
Weight is defined as the amount of _______ force acting on an object.
-
Answer: gravitational
-
Explanation: Weight is the force exerted on an object due to gravity. It is calculated as \( \text{Weight} = \text{Mass} \times \text{Gravity} \).
5.
Weight changes because of _______.
-
Answer: gravity
-
Explanation: Weight depends on the gravitational force acting on an object. Since gravity varies from place to place (e.g., Earth vs. Moon), weight changes accordingly.
6.
There is no force of gravity in _______.
-
Answer: space
-
Explanation: In outer space, far from any massive objects, the gravitational force is negligible, leading to a state of "weightlessness."
7.
Astronauts float in the space or in their spacecraft due to _______.
-
Answer: weightlessness
-
Explanation: Astronauts experience weightlessness because there is no significant gravitational force acting on them in space.
8.
Weight is measured in _______.
-
Answer: newton
-
Explanation: The standard unit for measuring weight (a force) is the newton (N).
9.
If an object goes into the space its _______ changes.
-
Answer: weight
-
Explanation: When an object moves into space, its weight changes because the gravitational force acting on it decreases.
10.
An object weighs _______ at sea level than at the top of a mountain.
-
Answer: more
-
Explanation: At sea level, the gravitational force is stronger compared to the top of a mountain due to the Earth's curvature and altitude. Therefore, an object weighs more at sea level.
