Icy98 said:Homework Statement
What is the acceleration of a body which is moving in opposite direction(assuming negative velocity) and is speeding up?
Homework Equations
acceleration=the rate of which an object changes its velocity
The Attempt at a Solution
In my opinion, an object moves with a negative velocity and is speeding up can be regard as having negative acceleration. This is what I learn from the notes provided on Physics Classroom. Is this correct?
Icy98 said:So if the object is moving in opposite direction but it is slowing down, hence it has positive acceleration?
Acceleration is the rate at which an object changes its velocity over time. It is measured in meters per second squared (m/s²).
Acceleration can be calculated by dividing the change in velocity by the change in time. The formula for acceleration is a = (vf - vi) / t, where vf is the final velocity, vi is the initial velocity, and t is the time interval.
Yes, acceleration can be both positive and negative. A positive acceleration means the object is speeding up, while a negative acceleration means the object is slowing down.
Negative velocity refers to the direction of an object's motion. If an object has a negative velocity, it is moving in the opposite direction of a chosen positive direction. Negative velocity can affect acceleration by either increasing or decreasing it, depending on the direction of the acceleration and the object's velocity.
When an object has a negative velocity and speeds up, it means that the object is slowing down in the direction of its motion. This can be caused by an opposing force acting on the object, such as friction or air resistance. In this case, the acceleration will be negative, but the object will still be speeding up in the opposite direction of its negative velocity.
