تدريب عام: Unit 4 : Concept 4.1 Effects of Gravity (Science) - Primary 5 - Science

السؤال 1

Besides mass, which other properties of the balls are compared in the investigation to observe gravity's effects?

Temperature and texture

Color and smell

Shape and size

Brightness and sound

السؤال 2

Asking "Why is the boy on the slide moving toward the ground?" exemplifies a step in scientific inquiry.

False

True

السؤال 3

What is the main purpose of attaching a small weight to the end of a string when demonstrating gravity's effect in an investigation?

To clearly show the direct line of the gravitational pull.

To make the string glow in the dark.

To prevent the string from tangling with other objects.

To increase the total tension in the string.

السؤال 4

What primary force keeps planets in orbit around a star?

Electromagnetic force

Nuclear force

Frictional force

Gravitational force

السؤال 5

Magnets can only exert a pull force on objects.

False

True

السؤال 6

Which action primarily demonstrates a push force?

A magnet attracting a paper clip.

Gravity pulling a dropped glass.

A foot exerting a force against the ground.

Earth attracting the Moon.

السؤال 7

Gravity causes objects like oil being poured to move downwards.

False

True

السؤال 8

What is a direct effect of the sun's powerful gravitational force on planets?

Planets revolve around the sun in fixed orbits.

Planets remain stationary.

Planets accelerate away from the sun.

Planets fly off into space.

السؤال 9

The angle measurements in the meterstick experiment indicate how the string aligns relative to the tilted meterstick under gravity's influence.

False

True

السؤال 10

What would happen to a boy on a slide if there were no gravity?

The boy would not slide down at all.

The boy would slide up the slide.

The boy would slide down faster.

The boy would float above the slide.

السؤال 11

How does the mass of an object influence its gravitational force?

As an object's mass increases, its gravitational force also increases.

An object's mass has no effect on its gravitational force.

As an object's mass increases, its gravitational force decreases.

Gravitational force only depends on an object's volume, not its mass.

السؤال 12

What is the purpose of using a balance or scale at the beginning of the 'Gravity and Motion' investigation?

To determine the volume of each ball before the experiment.

To compare the flexibility of different ball materials.

To ensure all balls have identical weights for a fair comparison.

To measure and record the mass of each ball before dropping them.

السؤال 13

Why is it a common scientific practice to take multiple measurements and calculate their average during an experiment?

To enhance the accuracy and reliability of the collected data.

To minimize the total number of experimental trials.

To ensure the experiment is more complex and challenging.

To guarantee equal participation among all team members.

السؤال 14

What constitutes the Solar System?

Only Earth and its moon.

The sun and the group of surrounding planets.

Any planet revolving around any star.

All the stars and galaxies in the universe.

السؤال 15

Gravity is considered a universal law because it affects objects consistently, regardless of their size or location in the universe.

False

True
