Can you Help Me! Physics Problem?

Only the last one,
There is a nonzero net force acting on the object.

It requires a force to accelerate any object. If forces add to zero, no acceleration.
 
If you are told an object is accelerating, what should you conclude? Choose all that apply.

The object is moving with a constant velocity.
The object is slowing down.
The object is speeding up.
The object is changing direction.
There is a nonzero net force acting on the object
 
The last one (There is a nonzero net force acting on the object) is definitely true.

At least one, maybe two, of the middle three (The object is slowing down, The object is speeding up, or The object is changing direction) is true, because of the force.

The first one (The object is moving with a constant velocity) is definitely not true.
 
you can apply the statements 2, 3, and 4.
reason: acceleration is rate at which velocity changes. so it can slow down or speed up. a change in direction means a variable velocity so it has acceleration.
1 and 2 can't be applied. because in constant velocity you have no acceleration. and without a force there is no acceleration.
