# Motion with Constant Acceleration (True/False)

• FAJISTE
In summary, the key points of this conversation are: acceleration is a vector quantity and direction matters, velocity changes by a certain amount each second, and position can change both positively and negatively depending on the origin and direction of acceleration.

## Homework Statement

If an object moves with constant (non-zero) acceleration, then which of the following statements are true?
The velocity must continually change by the same amount each second
The acceleration must be constant
The velocity must continually change by varying amounts depending on the speed
The velocity must be increasing
The position must be increasing

## The Attempt at a Solution

1. (Not sure) True, if acceleration is constant then the velocity will be linear meaning it changes by the same amount each time
2. Hm, not sure here. I'd go with false because can't the acceleration change from positive to negative and still remain constant?
3. False, velocity will go at same speed
4. False, could be negative acceleration
5. True

Some help please, not sure on some of them

1) acceleration is (m/s)/s which means it is changing by a certain velocity each second.
2) acceleration is a vector quantity, direction matters
3) same as question one, velocity changes by a certain amount each second.
5) position could also be changing negatively, it depends on the origin and direction of acceleration.

You should work for the Government.

It changes yet it can remain constant?

lol that was pretty dumb.

dude don't worry at least you gave it a lot more thought then some people would have.
just remember with vector quantities like accelaration and displacement and velocity, direction matters.

Yeah, i got it now thanks for the help.

## 1. Is it true that an object with constant acceleration will have a constant velocity?

No, an object with constant acceleration will not have a constant velocity. While the object's velocity will increase at a constant rate, its velocity will not remain the same.

## 2. Can an object have a constant acceleration if its velocity is changing?

Yes, an object can have a constant acceleration even if its velocity is changing. This is because acceleration is a measure of how quickly an object's velocity is changing, not the velocity itself.

## 3. Is it true that an object with constant acceleration will always have a linear motion?

No, an object with constant acceleration does not necessarily have to have a linear motion. While a constant acceleration will result in a linear motion, an object can also have a curved path if it has a constant acceleration towards a fixed point.

## 4. Can an object with constant acceleration have a negative velocity?

Yes, an object with constant acceleration can have a negative velocity. This can occur if the object is experiencing a deceleration, or a decrease in velocity, which is still considered a constant acceleration because the velocity is changing at a constant rate.

## 5. Is it true that an object with zero acceleration will always have a constant velocity?

Yes, an object with zero acceleration will always have a constant velocity. This is because zero acceleration means that the object is not changing its velocity, so it will continue to move at a constant speed.
