When is acceleration opposite to the direction of motion?
Acceleration is opposite to the direction of motion when the velocity of an object is decreasing. This occurs when the net force acting on the object is in the opposite direction of its motion, causing it to slow down.
When does something accelerate in the direction opposite to its direction of motion?
An object accelerates in the direction opposite to its motion when a force acts in the opposite direction to its velocity. This is known as deceleration or negative acceleration, and it occurs when there is a force opposing the object's motion, causing it to slow down.
Which type of acceleration occurs in circlar motion?
In circular motion, centripetal acceleration occurs, which is the acceleration directed towards the center of the circular path. This acceleration is necessary to keep an object moving in a circle, as it continually changes the direction of the object's velocity.
What is the definition of non uniform motion in physics?
During uniform motion, velocity is constant, so there is zero acceleration. Non-uniform motion involves a change in velocity, which means there is acceleration. Accelaration is a change in velocity. A change in velocity occurs when a body slows down, speeds up, or turns (changes direction), or a combination of these.
Can a body have no velocity and still have acceleration?
Yes, it is possible for a body to have zero velocity but still have acceleration. This occurs when the body is changing its direction of motion, even though its speed remains constant. The acceleration in this case is due to the change in direction, not speed.

When are velocity and acceleration perpendicular to each other?
Velocity and acceleration are perpendicular to each other when the magnitude of the acceleration is equal to the centripetal acceleration required for circular motion, and the direction of the acceleration is towards the center of the circular path while the velocity is tangent to the path. This occurs in uniform circular motion.
The acceleration that occurs in circular motion?
The acceleration that occurs in circular motion is called centripetal acceleration. It is directed towards the center of the circle and is responsible for keeping an object moving in a circular path. Centripetal acceleration is required because the direction of an object's velocity is constantly changing in circular motion.
Differentiate positive acceleration and negative acceleration?
A positive acceleration is a change in velocity such that the latter velocity is greater than the former velocity and is therefore going fasterwhile a negative acceleration or deceleration is a change in velocity such that the latter velocity is lesser than the former velocity and is therefore going slower.Now let us look at the equation of a uniform acceleration (the change in velocity is uniform):a = (vf-vi)/sIf the final velocity is greater, you will have a positive acceleration. If the initial velocity is greater, you will have a deceleration.
What orientation of velocity and acceleration will cause something to initialy slow down?
If the velocity and acceleration are in opposite directions, the object will initially slow down. This occurs when the acceleration is in the direction opposite to the object's motion, creating a deceleration effect.
What are the two types of motion that result from zero acceleration?
Rest and constant velocity.
Acceleration takes place when?
Acceleration occurs when there is a change in an object's velocity, either in magnitude or direction. This change can result from an increase or decrease in speed, or a change in the object's path of motion. Acceleration is a vector quantity, meaning it has both magnitude and direction.
Acceleration occurs when an object?
Changes direction.
