# Can velocity and acceleration be opposite to each other?

Can velocity and acceleration be opposite to each other? Yes, that is possible. You can have a body with positive velocity but negative acceleration (i.e. retardation actually). So, assume a car moving with an initial velocity of 10m/s in +ve x direction but then having a negative acceleration of -5m/s^2 in +ve x direction.

Can a velocity and acceleration be at different direction? Solution : Yes, Velocity of a body and its acceleration may be in different directions.

What is the relationship between velocity and acceleration? Acceleration is the rate of change of velocity. (when velocity changes -> acceleration exists) If an object is changing its velocity, i.e. changing its speed or changing its direction, then it is said to be accelerating. Acceleration = Velocity / Time (Acceleration)

Is acceleration always in the same direction as the force? As we know from Newton’s laws, objects which are accelerating are experiencing a net force. While the net force may not be in the same direction which the object is moving, it is always in the direction that the object is accelerating.

## Can velocity and acceleration be opposite to each other? – Additional Questions

### Can a body have velocity in one direction and acceleration in opposite direction?

Answer: Yes, a body can have acceleration and velocity in opposite directions. Examples: A body thrown upwards vertically. (gravity is then acting in the opposite direction)

### What happens when velocity and acceleration are not in the same direction what kind of motion occurs?

What happens when the velocity and acceleration are not in the same direction? What kind of motion occurs? You get a curved motion.

### Does the acceleration have direction?

Because acceleration has both a magnitude and a direction, it is a vector quantity. Velocity is also a vector quantity. Acceleration is defined as the change in the velocity vector in a time interval, divided by the time interval.

### Can an object’s acceleration be in opposite direction to its motion?

If the object is slowing down then its acceleration vector is directed in the opposite direction as its motion (in this case, a negative acceleration).

### What is the meaning of acceleration in opposite direction?

Acceleration = Rate of change of velocity. When acceleration is in opposite direction to velocity, it is called as negative acceleration or retardation.

### Can you give an example in which the acceleration of a body is opposite in direction to its velocity?

The acceleration of an object is in a direction opposite to its velocity when its velocity is decreasing–for example, a ball rising or a car braking to a stop.

### What kind of acceleration is opposite to the direction of velocity?

According to our principle, when an object is slowing down, the acceleration is in the opposite direction as the velocity. Thus, this object has a negative acceleration. In Example D, the object is moving in the negative direction (i.e., has a negative velocity) and is speeding up.

### Can the velocity of an object reverse direction while maintaining a constant acceleration?

Yes, the velocity of the object can reverse direction when its acceleration is constant. For example consider that the velocity of any object at any time t is given as: v(t) = t – 2. At At t = 0 sec, the magnitude of velocity is 2m/s and is moving in the forward direction i.e.v (t) = -2.

### Can the velocity of an object be negative when its acceleration is positive?

Yes, it is possible to have negative velocity when acceleration is positive. Consider a body or an object moving in a negative direction, having a negative velocity and acceleration. If the object slows down, its acceleration vector will be in the opposite direction from its motion, i.e., positive.

### Can both the velocity and acceleration be negative at the same time?

If velocity and acceleration have opposite signs, you slow down. Show activity on this post. Negative velocity = You move backwards. Negative acceleration = You slow down or you go faster in the backwards direction.
