Question

If a constant, nonzero force is applied to an object, what can you say about the velocity and acceleration of the object?

Step-by-Step Solution

Answer

With the application of nonzero force, the velocity of the object changes, and the object accelerates.

Step 1: Concept of Newton’s second law of motion

Newton’s second law of motion states that the acceleration of a system is directly proportional to the net external force acting on the system and is inversely proportional to the mass of the system. Mathematically,

$F_{net}=ma$

Here$F_{net}$is the net force,${}^m$is the mass, and${}^a$ is the acceleration.

Step 2: The effect of nonzero force on the velocity and acceleration of the object

When a constant, nonzero force is applied to an object, then the object starts to accelerate. The acceleration of the body clearly indicates that the velocity of the object is changing.

 

Therefore, with the application of nonzero force, the velocity of the object changes, and the object accelerates
