An object that does not accelerategneill said:Hi Swag ranger,
Welcome to Physics Forums.
What do you know about inertial reference frames? How are they defined?
No, not quite. A reference frame is not necessarily associated with a particular object. It's a coordinate system that has particular properties (particularly with respect to other inertial reference frames).Swag ranger said:An object that does not accelerate
An inertial reference frame is a coordinate system in which the laws of physics hold true and objects remain at a constant velocity unless acted upon by an external force.
Acceleration in an inertial reference frame is defined as the rate of change of velocity over time. It can be calculated by dividing the change in velocity by the change in time.
In an inertial reference frame, acceleration is caused by an external force acting on an object. In a non-inertial reference frame, acceleration can also be caused by the frame itself accelerating.
Yes, acceleration in an inertial reference frame can be negative if the object is slowing down or accelerating in the opposite direction of its initial velocity.
Examples of acceleration in an inertial reference frame include a car accelerating from a stop, a ball falling due to gravity, and a rocket launching into space.
