What else can I help you with?
In a wheel and axle what usually exerts the resistance force?
wheel
What is a contraction in which the muscle shorten and work is done?
This is muscle flexion or isotonic contraction.
When a pencil sharpener is used which moves a greater distance the handle (wheel) or the sharpening mechanism (axle) which exerts greater force?
The handle (wheel) moves a greater distance than the sharpening mechanism (axle). The handle exerts greater force as it must overcome the resistance of the pencil being shaved and the friction in the sharpener.
Thr force air exerts on a moving object?
Air resistance
The force air exerts on a falling object is known as?
air resistance
The contraction of a muscle exerts a pull on a bone because?
the muscle is attached to the bone via tendons, which transmit the force generated by the muscle contraction to the bone. This pull causes the bone to move, allowing for various types of body movements like walking or lifting objects.
Does air exerts force?
Yes, air exerts a force on objects due to its pressure. This force is known as air pressure and can influence the behavior of objects in various ways, such as causing them to move or providing support.
What energy transfer is door was opened?
When a door is opened, mechanical energy is transferred from the person opening the door to the door itself. The person exerts a force to overcome the resistance of the door, causing it to move and change its position. This energy transfer is an example of mechanical work being done.
What type of friction exerts the least force?
Static friction exerts the least force because it opposes the initiation of motion rather than the motion itself, resulting in less resistance.
What is it called when Force applied to a simple machine?
When a force is applied to a simple machine, it is called input force. This force is used to overcome resistance or mechanical advantage within the machine to perform work. The input force is typically different from the output force, which is the force the machine exerts to accomplish a task.
Is the Earth exerts on the Moon a force acting at a distance?
False,since it's an air resistance and it's a contact force.
What are the similarities between a spring scale and a triple beam balance?
Both are analog measuring devices, meaning they convert mechanical energy into a numerical measurement. And both work on the principle of measuring the weight of an object by measuring the force it exerts against resistance. In the spring's case, the object being weighed is trying to overcome the spring's tension; while with the balance scale, the object is trying to overcome the force exerted by the counterweights.
