You input potential (stored) energy into the rubber band system when you stretched the rubber band back. Because it is an elastic system, this kind of potential energy is specifically called elastic potential energy. When the rubber band is released, the potential energy is quickly converted to kinetic (motion) energy.
When we stretch a rubber band the elastic potential energy?
We know that potential energy is also a form of stored energy so while stretching a rubber band a potential energy will be stored resulting in an increase of it. Hence we can say that potential energy is increased when the rubber band is stretched. So, the correct answer is “Option C”.
What happens to elastic potential energy when stretched?
The elastic properties of a spring depends on both shape and the material of the spring. Therefore, the elastic constant is different for every object. Elastic potential energy increases with the constant of the spring and with the distance stretched.
What happens when you stretch a rubber band?
A rubber band is an elastic material in nature. When stretched, it changes its shape and when the applied force is removed, it regains its original shape. That is why a rubber band changes its shape even though it is a solid. Also, if excessive force is applied then the rubber band would break.
Would stretching a rubber band increase or decrease the amount of elastic potential energy it has?
The rubber bands have the same amount of elastic energy no matter how much they are stretched.
How do you calculate elastic energy?
Energy stored in a spring Work is done when a spring is extended or compressed . Elastic potential energy is stored in the spring. The elastic potential energy stored can be calculated using the equation: elastic potential energy = 0.5 × spring constant × (extension) 2.
What are some examples of elastic potential energy?
Many objects are designed specifically to store elastic potential energy, for example: The coil spring of a wind-up clock. An archer’s stretched bow. A bent diving board, just before a divers jump. The twisted rubber band which powers a toy airplane. A bouncy ball, compressed at the moment it bounces off a brick wall.
Does a stiffer spring have more elastic potential energy?
A less stiff object can be stretched or compressed more easily. Comparing two elastic objects, more elastic spring force would act on the stiffer elastic object when they are stretched or compressed by the same length.
What kind of energy does a rubber band have when it is stretched?
You input potential (stored) energy into the rubber band system when you stretched the rubber band back. Because it is an elastic system, this kind of potential energy is specifically called elastic potential energy.
What factors affect elastic potential energy?
The factors that determine the amount of elastic potential energy being stored include the type of material and the amount it is deformed. The more an object is deformed, the more stored energy it has.
What happen when you stretch the paperclip?
If we bend the paper clip just a little, it snaps back to its original shape. Stretch or bend certain metals (like, for example, the hardened steel of hacksaw blades) and, instead of deforming like paper clips, they just go plink — they break in two all at once.
Does a rubber band stretch when weight is applied?
If you get hold of a rubber band and pull it you are using a force on it. That force makes the rubber band get longer – it stretches. The greater the pull the longer it gets. In other words a bigger force makes the rubber band stretch more.
What happens when you stretch the rubber bands will it become longer or shorter Why?
As the rubber is stretched the bonds between adjacent chains are broken. Stretching a rubber band makes it get hot – heat energy is lost. Therefore if you put heat energy into a rubber band it will get shorter – unlike most materials when they are heated.
Does a rubber band sitting on a table have stored potential energy?
Elastic – Elastic potential energy is stored when materials stretch or compress. Examples of elastic potential energy include springs, rubber bands, and slingshots.
Does elastic potential energy depend on mass?
Common types of potential energy include the gravitational potential energy of an object that depends on its mass and its distance from the center of mass of another object, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field.
How much can a rubber band stretch?
How much does silicone rubber stretch? Some Silicone rubbers can stretch up to 1000%! (That’s about 100x its original length!) Typically the softer the silicone the more it stretches, 20 shore will stretch a lot more than an 80 shore grade.
What is elastic energy used for?
The elastic potential energy equation is used in calculations of positions of mechanical equilibrium. The energy is potential as it will be converted into other forms of energy, such as kinetic energy and sound energy, when the object is allowed to return to its original shape (reformation) by its elasticity.
What factors affect kinetic energy?
The two main factors that affect kinetic energy are mass and speed. Why? Because the motion of an object depends on how fast it’s traveling, but also how much mass it has, though velocity is the more important factor.
What are 3 examples of gravitational potential energy?
Examples of Gravitational Potential Energy A raised weight. Water that is behind a dam. A car that is parked at the top of a hill. A yoyo before it is released. River water at the top of a waterfall. A book on a table before it falls. A child at the top of a slide. Ripe fruit before it falls.
How does temperature affect elastic potential energy?
When the ball is heated, it becomes more elastic, as the bonds are able to move more freely and thus are able to stretch more than those in a cooler ball, and thus less energy is lost (Portz, 2011). This then means that the ball bounces higher.
Is elastic potential energy always positive?
So, the motion involves net increase of potential energy whether it is being compressed or elongated. Hence, in that sense, change in potential energy is always positive, in this case, as John Rennie has mentioned in his post.
