This is not true. Acceleration includes direction, but speed does not. Speed in a particular direction is called velocity.

### Both speed and acceleration include the direction of an objects motion?

Yes! In most problems direction needs to be defined as either positive or negative.

### When you know both the speed and direction of an objects of an objects motion you know the?

I'm pretty sure its the acceleration. If its not that, its the Velocity.

### Acceleration is a change in speed or?

Acceleration is the change in an ogjects speed or a change in an objects direction of motion or both of these. If instead of speed you use the word velocity , which is both an object's speed and its direction of motion, then you could say "acceleration is the change in an objects velocity" and that would cover all the possibilities in one statement.

### Can an object be moving if acceleration is zero?

Yes. Acceleration is defined as a change of speed and/or direction of motion. If the speed and direction of motion are constant, then there is no acceleration.

Acceleration

### What kind of motion does the speed and direction not change?

Acceleration in motion refers to a change in speed or direction of that object's motion. So a type of motion in which speed and direction do not change is a motion in which the acceleration is constant (i.e. unchanging).

### True or false acceleration is a change in motion?

'Acceleration' is a change in the speed and/or direction of motion.

### How does the direction of acceleration affect the directions of motion?

The acceleration will either speed up or slow down an object's motion in the direction it is applied. Any change in speed or direction is considered acceleration.

### When you both the speed and direction of an objects motion you know the objects?

translatory motion

### The resistance of an object to changes in its motion?

The resistance of an object to changes in its motion is known as inertia. Changes in an objects motion include changes in its speed and direction.

### What is the example where acceleration is in the direction of motion?

An example of acceleration in the direction of motion is a smooth spherical stone dropped from the roof of a building on a windless day. All the motion is straight down, toward the center of the earth, and so is the acceleration.

### What do displacement and acceleration have in common?

They are related to the motion of objects.
