the car is at a constant speed
---------------------------------------------------------
I'm pretty sure that if the acceleration is negative, the car is slowing down. But if the velocity is negative, the car is either heading south or down (velocity refers to speed and direction.. according to my physics teacher).
What else can I help you with?
Can acceleration ever be negative?
Acceleration is negative when the object is moving in the opposite direction. on a graph the line would be in the negative quadrant.
When an object is speeding up to the right what direction is the acceleration?
The acceleration would be in the direction of the object's motion, which is to the right.
How does positive and negative acceleration affect motion?
positive acceleration helps to increase the velocity for positive direction while negative acceleration resists the motion.
If velocity is positive which would most likely yield a negative acceleration?
If an object is moving in the positive direction, a negative acceleration would most likely occur if the object is slowing down, such as when it is decelerating or coming to a stop. Negative acceleration indicates that the object's velocity is decreasing over time.
What type of motion would produce positive acceleration in an object?
Positive acceleration in an object can be produced by a force applied in the direction of its motion. This force will cause the object to increase its speed over time.
Can acceleration ever be negative?
Acceleration is negative when the object is moving in the opposite direction. on a graph the line would be in the negative quadrant.
How can an object slowing down have an acceleration that's not negative?
If the positive direction was defined at the outset as the direction opposite to the direction in which the object happens to be moving just now, and the object is slowing down, then the acceleration is positive because, algebraically, the object's speed is increasing in the positive direction.
When an object is speeding up to the right what direction is the acceleration?
The acceleration would be in the direction of the object's motion, which is to the right.
If you could hypothetically drill a hole through the center of the earth would a object dropped in to the hole enter SHM simple harmonic motion?
Yes it would as the acceleration is always be towards the centre and the acceleration would be directly proportional to the negative of the deplacement of the object.
How does positive and negative acceleration affect motion?
positive acceleration helps to increase the velocity for positive direction while negative acceleration resists the motion.
If velocity is positive which would most likely yield a negative acceleration?
If an object is moving in the positive direction, a negative acceleration would most likely occur if the object is slowing down, such as when it is decelerating or coming to a stop. Negative acceleration indicates that the object's velocity is decreasing over time.
What type of motion would produce positive acceleration in an object?
Positive acceleration in an object can be produced by a force applied in the direction of its motion. This force will cause the object to increase its speed over time.
Can an object have both negative velocity and acceleration?
Yes, an object can have negative velocity and negative acceleration if it is moving in the opposite direction of the positive axis. This would mean the object is both moving backwards and its speed is decreasing.
What would you not use to find the acceleration of an object?
You would not use the object's mass to find its acceleration. Acceleration is determined by the force acting on an object, as given by Newton's second law of motion (F = ma), not by the object's mass alone.
Is an object in motion if the acceleration is zero?
Acceleration just means that something is getting faster at a constant pace. If the object was at rest it would have a constant velocity. If the object was then acted upon by and unbalanced force, the velocity would change and no longer be constant. However if an object is just moving along (balanced force of air resistance, gravity, and friction) then it would be at a constant velocity, also. In motion or at rest and object can have zero acceration.
Does an object that is moving in a linear path with an acceleration in the direction opposite to the motion have a decreasing velocity?
No. Acceleration is Delta-Velocity / Delta-Time. If Acceleration is negative then that means that either Delta Velocity is negative or Delta Time is negative---which is not practical. For Acceleartion to be negative, that means the Velocity has to Decrease. (where Delta Velocity is change in Velocity or V2 - V1)
Does acceleration have a negative or positive value if the velocity is increasing speed?
In this case, acceleration is positive. Negative acceleration would cause the object to slow down (decelerate.)
