Solving exercises from pages 31 and 32 of Physics 6, Elastic Force

Solving problem C1 from page 31 of Physics 6 textbook

Problem statement:

Find suitable words from the box to fill in the blanks of the following sentences:

When pulled by a weight, the spring (1) ............, its length (2) ................ When the weights are removed, the spring returns to (3) ................ length, its natural length. The spring regains its original shape.

Solution:

(1) stretches out

(2) increases

(3) equals.

Solving problem C2 from page 31 of Physics 6 textbook

Problem statement:

Calculate the deformation of the spring when hanging 1, 2, 3 weights, then record the results in the appropriate cells of table 9.1.

Solution:

Solving problem C3 from page 32 of Physics 6 textbook

Problem statement:

In the experiment illustrated in figure 9.2, when the weight is stationary, the elastic force exerted by the spring on it is balanced by which force?

Thus, the magnitude of the spring's elastic force will be equal to the magnitude of which force?

Solution:

- The elastic force exerted by the spring on the weight is balanced by the weight's gravitational force.

- The magnitude of the spring's elastic force will be equal to the magnitude of the gravitational force.

Solving problem C4 from page 32 of Physics 6 textbook

Problem statement:

Choose the correct sentence from the sentences below:

A. Elastic force is independent of deformation.

B. If deformation increases, elastic force decreases.

C. If deformation increases, elastic force increases.

Solution:

Answer C. If deformation increases, elastic force increases.

Solving problem C5 from page 32 of Physics 6 textbook

Problem statement:

Based on table 9.1, find the appropriate word to fill in the blank:

a) When the deformation doubles, the elastic force (1) ..................

b) When the deformation triples, the elastic force (2) ..................

Solution:

(1) doubles

(2) triples

Solving problem C6 from page 32 of Physics 6 textbook

Problem statement:

Answer the question posed at the beginning of the exercise.

'What similarity do a rubber string and a spring share?'

Solution:

A rubber string and a spring both possess elastic properties.

In the Physics 6 curriculum, Chapter I Mechanics, students will learn about Gravity. Force units. Let's solve exercises on pages 27, 28, 29 of Physics 6 to master this lesson.

In Chapter I Mechanics of Physics 6, students will explore the effects of forces and solve exercises on pages 24, 25, 26 of Physics 6.
