What else can I help you with?
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.
What can cause velocity to change?
acceleration, due to a force the moving body is affected by. SUM[Forces] = mass * acceleration --> change in speed.
Velocity can change causing?
Velocity change can result in changes in an object's speed and/or direction of motion. This change in velocity can be caused by forces such as acceleration, deceleration, or changes in direction, which can affect the object's kinetic energy and momentum.
What is deceleration in physics?
Deceleration in physics refers to the rate at which an object slows down its speed or velocity. It is the negative acceleration of an object moving in the opposite direction of its velocity vector, causing it to decrease its speed. Deceleration can occur due to various factors such as friction, air resistance, or external forces acting on the object.
What does apply forces to object balanced vs unbalanced?
Applying balanced forces to an object means the forces are equal in size and opposite in direction, resulting in no change in the object's motion. Applying unbalanced forces means the forces are unequal, leading to a change in the object's motion, such as acceleration or deceleration.
What are ways your velocity can change?
Any acceleration.Acceleration in physics is classed as loss or gain or speed, or any change in direction.
Why do you have to have negative acceleraton?
A negative acceleration, or deceleration, is the cause of unbalanced forces, where the force opposing the direction of travel is greater than the force along the direction of travel.
What is acceleration caused by?
Acceleration is caused by a change in an object's velocity over time. This change can result from forces such as gravity, friction, or applied forces. The direction of the force will determine the direction of the acceleration.
What is the definition of the word unbalanced forces?
When two or more forces act on an object, if the sum (vector sum) of the forces is zero, the forces are said to be balanced. Otherwise the forces are unbalanced. According to Newton's Second Law, an unbalanced force will cause an acceleration.
Acceleration is against the direction of motion?
Acceleration can be in the opposite direction of motion, which is called deceleration. Acceleration can also be in the same direction as motion, causing an increase in speed. The direction of acceleration depends on the forces acting on the object.
When does the velocity of an object change?
The velocity of an object changes when there is a change in its speed, direction, or both. This can occur due to external forces acting on the object, such as acceleration or deceleration, causing the velocity to increase or decrease.
What is the difference between balanced and unbalanced forces which circumstance can exert pressure Why?
Balanced forces have equal magnitude and opposite directions, resulting in no overall change in an object's motion. Unbalanced forces have unequal magnitude or are not opposite in direction, causing acceleration or deceleration of an object. Unbalanced forces can exert pressure by causing objects to move or change their speed or direction, such as when pushing or pulling an object.
