How does the of a 115kg barbell compare to the weight of the lifter?
The weight of a 115kg barbell is constant. The lifter's weight, however, will vary. If the lifter weighs less than 115kg, the barbell will be heavier relative to their weight. If the lifter weighs more than 115kg, the barbell will be lighter relative to their weight.
How does the force of the lifter compare with the weight of the barbell at different stage of the lifter?
At the beginning of the lift, the lifter's force is greater than the weight of the barbell to overcome inertia and initiate movement. During the middle of the lift, the lifter's force is equal to the weight of the barbell to maintain constant velocity. Towards the end of the lift, the lifter's force is less than the weight of the barbell due to deceleration and control.
If a weight lifter lifts a barbell and then sets it down is any work done?
Answer: It depends upon your definition of "work". Assuming the lifter put the barbell back exactly where and how it was at first, then there was no work done in the physics context. If you mean manual labor, then yes, some work was done.
What are the different types of barbell marks and how are they used in weightlifting?
There are two main types of barbell marks used in weightlifting: knurling and rings. Knurling provides grip for the lifter, while rings indicate where the lifter should place their hands for different exercises. Knurling helps prevent the barbell from slipping during lifts, while rings help ensure proper hand placement for optimal performance and safety.
A weight lifter lifs a barbell above her head and hold it there where can you infer about the work she is doing?
You can infer that she is working on building up her strength.
Can you use the word squatted in a sentence?
The immense jungle cat squatted silently on the tree limb, patiently awaiting his next meal. The muscular weight-lifter then squatted in front of the huge barbell.
What is the amount of work done by a weight lifter in holding a weight of 100kg on his shoulder for 40 seconds?
While just holding the weight on his shoulder, the weight lifter does no work! For work to be done, the mass must be moved through a distance … No Movement, No Work! (but don't tell that to a weight lifter …)
How can you tell if you have blown lifter?
You can tell if you have a blown lifter by get someone to count of 10 seconds for you and you need to count how many times the noise happens in the 10 seconds and then multiply by 6. That should give you a number. Take that number and then compare it to your idle RPM's. If it's the same as your idle RPMs, then it's likely bottom end knocking. If it's half as fast as your RPMs - then it's valvetrain, like a lifter or an exhaust leak.You can tell if you have a blown lifter by get someone to count of 10 seconds for you and you need to count how many times the noise happens in the 10 seconds and then multiply by 6.

What are the differences between performing a deadlift at an elephant bar compared to a normal barbell?
Performing a deadlift on an elephant bar, which is longer and more flexible than a normal barbell, can require more stability and control due to the increased length and bend of the bar. This can impact the lifter's grip, balance, and technique, making the lift more challenging and potentially requiring adjustments in form.
Explain how newtons 1st law applies to the clean and jerk?
Newton's 1st law states that an object will remain at rest or in uniform motion unless acted upon by an external force. In the clean and jerk, this law applies during the clean phase where the lifter accelerates the barbell from the floor to the shoulders by exerting force to overcome inertia. In the jerk phase, the law comes into play when the lifter applies force to lift the barbell overhead against gravity.
