What will happen if you keep on adding more padlocks to the spring balance?
Answer. Answer: The spring balance is that the spring will sag because it will be heavy to lift the spring balance on the padlock. The spring balance will be heavy due to the force carried by the padlock.
What is the reading accuracy of a spring balance?
18.2. Because the characteristics of the spring are very susceptible to environmental changes, measurement accuracy is usually relatively poor. However, if compensation is made for the changes in spring characteristics, then a measurement inaccuracy less than ±0.2% is achievable.
What are the effects of force on the size of an object?
A force acting on an object causes the object to change its shape or size, to start moving, to stop moving, to accelerate or decelerate. When there’s the interaction between two objects they exert a force on each other, these exerted forces are equal in size but opposite in direction.
What are the common ways you did to change the shape of the objects?
When a force acts on an object, the object may change shape by bending, stretching or compressing – or a combination of all three shape changes.
What 3 things can a force change about an object?
A force can do one of four things to an object:
- Make it speed up – accelerate.
- Make it slow down – decelerate.
- Change its direction.
- Change its shape.
Why does changing the shape of an object?
Changing the shape of an object will not change the density of an object because the mass and the volume stays the same. So then the density stays the same. Why does changing the shape of an object have no effect on the density of that object?
What do you call a push or pull on objects?
A force is a push or pull upon an object resulting from the object’s interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects.
What is the relativistic limit?
In general, the ultrarelativistic limit of an expression is the resulting simplified expression when pc ≫ mc2 is assumed. Or, similarly, in the limit where the Lorentz factor γ = 1/√1 − v2/c2 is very large (γ ≫ 1).
At what speed does time dilation become noticeable?
300,000 km per second
