Responses

Velocity is the speed of an object in a particular direction.
Velocity is the speed of an object in a particular direction. - no response given

Velocity is the sum of all of the forces acting on an object.
Velocity is the sum of all of the forces acting on an object. - no response given

Velocity is a force that changes an object's speed and/or direction.
Velocity is a force that changes an object's speed and/or direction. - no response given

Velocity is the resistance of an object to a change in its speed or direction.

Answer 1

The correct description of velocity is:

**Velocity is the speed of an object in a particular direction.**

The other statements provided do not accurately describe velocity. Here’s a brief explanation of the other statements:

1. **Velocity is the sum of all of the forces acting on an object.** - This describes net force, not velocity.

2. **Velocity is a force that changes an object's speed and/or direction.** - This describes acceleration or force, not velocity.

3. **Velocity is the resistance of an object to a change in its speed or direction.** - This describes inertia or mass, not velocity.

So, the first statement is the only one that correctly defines velocity.
