Question

the force that results from all the combined forces acting on the object is called the net force. calculate the net force acting on the box in the following problems. be sure to include the direction of the net force (left or right)! 1. 4 n ← net force: 2. 7 n ← 2 n net force: 3. 4 n → ← 4 n net force: 4. 6 n → → 3 n net force: 5. 8 n ← → 4 n net force: 6. 4 n → ← 5 n net force: 7. ← 3 n ← 3 n net force: 8. 2 n → ← 5 n 4 n → net force: 9. 6 n ← 3 n → net force: 10. 7 n ← → 4 n 4 n → net force:

Explanation:

Problem 1:

Step 1: Identify Forces

There is a single force of \( 4 \, \text{N} \) to the left.

Step 2: Calculate Net Force

Since there's only one force, the net force is \( 4 \, \text{N} \) to the left.

Problem 2:

Step 1: Identify Forces

Forces are \( 7 \, \text{N} \) left and \( 2 \, \text{N} \) right.

Step 2: Subtract Forces

Net force \( = 7 - 2 = 5 \, \text{N} \) (left, as \( 7 > 2 \)).

Problem 3:

Step 1: Identify Forces

Forces are \( 4 \, \text{N} \) right and \( 4 \, \text{N} \) left.

Step 2: Subtract Forces

Net force \( = 4 - 4 = 0 \, \text{N} \) (balanced).

Problem 4:

Step 1: Identify Forces

Forces are \( 6 \, \text{N} \) right and \( 3 \, \text{N} \) right.

Step 2: Add Forces

Net force \( = 6 + 3 = 9 \, \text{N} \) to the right.

Problem 5:

Step 1: Identify Forces

Forces are \( 8 \, \text{N} \) left and \( 4 \, \text{N} \) right.

Step 2: Subtract Forces

Net force \( = 8 - 4 = 4 \, \text{N} \) to the left.

Problem 6:

Step 1: Identify Forces

Forces are \( 4 \, \text{N} \) right and \( 5 \, \text{N} \) left.

Step 2: Subtract Forces

Net force \( = 5 - 4 = 1 \, \text{N} \) to the left.

Problem 7:

Step 1: Identify Forces

Two forces of \( 3 \, \text{N} \) left.

Step 2: Add Forces

Net force \( = 3 + 3 = 6 \, \text{N} \) to the left.

Problem 8:

Step 1: Identify Forces

Right forces: \( 2 + 4 = 6 \, \text{N} \); left force: \( 5 \, \text{N} \).

Step 2: Subtract Forces

Net force \( = 6 - 5 = 1 \, \text{N} \) to the right.

Problem 9:

Step 1: Identify Forces

Forces are \( 6 \, \text{N} \) left and \( 3 \, \text{N} \) right.

Step 2: Subtract Forces

Net force \( = 6 - 3 = 3 \, \text{N} \) to the left.

Problem 10:

Step 1: Identify Forces

Right forces: \( 4 + 4 = 8 \, \text{N} \); left force: \( 7 \, \text{N} \).

Step 2: Subtract Forces

Net force \( = 8 - 7 = 1 \, \text{N} \) to the right.

7. \( 6 \, \text{N} \) to the left
8. \( 1 \, \text{N} \) to the right
9. \( 3 \, \text{N} \) to the left
10. \( 1 \, \text{N} \) to the right
