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.
What is the force that causes the velocity of an object to change?
The force that causes the velocity of an object to change is called acceleration. Acceleration is defined as the rate at which an object's velocity changes over time, and it can be caused by various factors such as gravity, friction, or applied forces.
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.
Why is an object traveling in a circular motion?
acceleration is change in velocity.. and velocity constantly changes in circular motion, as the direction constantly changes. This constant change in velocity causes the object to accelerate.
What is the force that causes a change of velocity when acting on an object?
Opposing force
How do forces cause an object to change its speed?
A forces on an object m creates an acceleration a=f/m and acceleration causes a change in velocity a= dv/dt. This change in velocity can change the speed or direction or both.
How do forces cause a change in an object's momentum?
A force acting on a body causes acceleration. Acceleration is measure of the rate of change in the object's velocity. As its velocity changes, its momentum, which is the product of its mass and velocity, will change.
What causes the change in velocity?
A change in velocity can be caused by forces acting on an object. These forces can be due to interactions with other objects, such as a push or a pull, or due to internal processes like propulsion systems. Changes in velocity can also occur due to changes in direction, such as when an object turns.
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.
Why does impulse affect momentum?
Impulse is defined as the change in momentum of an object. When a force is applied to an object over a period of time, it causes a change in the object's velocity, which in turn affects its momentum. Therefore, impulse affects momentum by altering the velocity of an object, leading to a change in its momentum.
The change in an object velocity?
The change in an object's velocity is determined by its acceleration. If the object's acceleration is positive, its velocity increases; if it is negative, the velocity decreases. The larger the acceleration, the quicker the change in velocity will be.
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".
