Use a ruler, a pivot, some weights. set the experiment by putting the pivot then a ruler on top of it finally put the wights on each end of the ruler
Complete question is;
When you ride a bicycle, in what direction is the angular velocity of the wheels? A) to your left B) to your right C) forwards D) backwards
Answer:
Option A - to your left
Explanation:
While an object rotates, each particle will have a different velocity:
the 'Speed' component will vary with radius while the 'Direction' component will vary with angle.
All of the velocity vectors are aligned in the same plane.
We can be solve this by choosing a single vector normal to ALL of the possible velocity vectors of the rotating object in that plane.
This convention used is known as "Right-hand rule". The angular velocity vector points along the wheel's axle. For instance, if you Imagine wrapping your right hand around the axle so that your fingers point in the direction of rotation, with your thumb sticking out. You will notice that your thumb points to the left.
Thus;
By right-hand rule, a wheel rotating on a forward - moving bicycle has an angular velocity vector pointing to the rider's left.
So, option A is the correct answer
Answer:
We can easily find out the beginning point of the line by using dot representation.
When it comes to position vector, it expresses the exact position of certain object from the starting point of the coordinate system.
The vector is a straight line that has a certain end which is fixed to its body.
The other end is linked with a moving point that tells an accurate position of that specific point.
False because the first law of motion is the crash I think I’m in middle school
I think unbalanced forces is one of the reasons
