Which of the following is an inertial reference frame? check all that apply. check all that apply. a reference frame that is moving downward at a constant speed a reference frame that is motionless a reference frame that is moving upward at a constant speed a reference frame that is rotating at a constant speed?

Inertial reference frames

a reference frame that is moving downward at a constant speed

a reference frame that is motionless

a reference frame that is moving upward at a constant speed

Explanation:

An inertial frame of reference is a frame of reference in which the Newton's laws are valid. The frame in which the objects have the property of inertia is called an inertial frame. In this frame the objects do not accelerate without external force. All frames of reference moving with constant velocity or at rest relative to an inertial frame of reference are also inertial frames of reference

In a non-inertial frame of reference, the Newton's laws will not work. They are moving with an acceleration.

So in the given option the first three are fitting with the definition for the inertial frame of reference.

But the Fourth is not an inertial frame. Because it is changing direction when rotating.

Velocity is the speed with direction. When the direction changes the velocity also changes (even if the speed is constant).

Inertia reference frames are:

A Reference frame that is moving upward at a constant speed

B reference frame that is moving downward at a constant speed

C reference frame that is motionless

This also implies the correct answer is a, b, and c.

A frame of reference refers to a coordinate system that is attached or connected to a rigid body.

For instance, if a body is in motion with a constant speed, the frame is referred to as an Inertial frame. In an initial frame, the application of Newton’s law can determine the dynamics of every particle.

Also, the frame will be non-inertia if the body where the imagined frame is attached is accelerating. In a non-inertia frame, newton’s law would not be applicable because the body is moving with acceleration.

Simply put, any frames of reference that move with a constant speed or velocity are called inertial frames. Therefore, from the answer’s choice provided, option a, b, and c, all fits the definition of an inertial frame of reference.

However, option d does not represent inertial frame because the frame rotates at a constant velocity.

Thus, inertial reference frames are: Reference frame that is moving upward at a constant speed, reference frame that is moving downward at a constant speed and reference frame that is motionless
