Chapter 3, Problem 41R

To determine

The factor with which an object always accelerates in the same direction.

Answer to Problem 41R

An object always accelerates in the same direction of net force and the correct option is option (A).

Explanation of Solution

Introduction:

The net forces is calculated by using following expression when an object accelerates.

  $F=ma$

Here,

• $m$ is the mass.
• $a$ is acceleration due to gravity.

A moving object always accelerates in the direction of motion. The algebraic sum of all the forces represents the net force acting on an object. The net force is accountable for developing the acceleration in the object.

For example: If a force of 8 N acts on an object and this vehicle feels a friction force of 2 N, the net force on this vehicle will be 6 N and object will accelerate in the forward direction.

Conclusion:

Therefore, an object always accelerates in the same direction of net force.
