What is a change in velocity or direction?
Any change in speed or direction is a change in velocity. That's an acceleration,and it directly implies the presence of force, since it can't happen without force.
Can direction of velocity of a body change when its acceleration is constant?
Yes, the direction of velocity of a body can change even when its acceleration is constant. This can happen if the acceleration and initial velocity of the body are not aligned in the same direction. The body will still experience a change in velocity due to the constant acceleration, which can lead to a change in direction.
Describe a situation in which gravity causes a change in velocity why does a change in velocity happen?
When an object is dropped from a height, gravity causes it to accelerate towards the ground. This acceleration leads to a change in velocity as the object's speed increases. The change in velocity occurs because gravity exerts a force on the object, pulling it towards the Earth.
When the body will possess non uniform velocity?
The body will possess non uniform velocity when its speed is changing over time, either increasing or decreasing. This can happen when the body is accelerating or decelerating, causing its velocity to be different at different points during its motion.
What is a situation gravity causes a change in velocity and why does the change of velocity happen?
A situation where gravity causes a change in velocity is when an object is dropped from a height. As the object falls, gravity acts on it, causing it to accelerate towards the ground. The change in velocity happens because gravity exerts a constant force on the object, causing it to increase its speed over time.
How can velocity change even if speed stays the same?
Velocity is a vector quantity that includes both speed and direction. If the direction of motion changes while the speed remains constant, then the velocity will change. This can happen when an object moves in a circular path, for example.
How do you calculate the change in velocity of an object?
To calculate the change in velocity of an object, you subtract the initial velocity from the final velocity. The formula is: Change in velocity Final velocity - Initial velocity.
When velocity may change?
Velocity may change when an object experiences a change in speed or direction. This can occur when a force is applied to the object, causing it to accelerate or decelerate. Changes in velocity can also happen if an external force opposes or alters the object's motion.
What must happen for acceleration to occur?
For acceleration to occur, there must be a change in an object's velocity over time. This change can happen by increasing or decreasing the object's speed or by changing its direction of motion. In essence, acceleration is a measure of how much an object's velocity changes per unit of time.
Where can change in vector quantity?
A change in a vector quantity can occur in its magnitude, direction, or both. This change can happen when there is acceleration or deceleration, change in velocity direction, or when there are forces acting on the object.
Rate of change of the velocity of an object?
The change in velocity is just the change in velocity. The RATE of change of velocity - how quickly velocity changes - is usually called "acceleration".
What is the range of change of velocity?
The range of change of velocity is determined by the final velocity minus the initial velocity. It represents the magnitude and direction of the change in velocity of an object.
