Take a toy car. Wind it using its key.
Place the car on the ground.
Did it move?
From where did it acquire energy?
Does the energy acquired depend on
the number of windings?
How can you test this?
Answers
Acquires potential energy
Explanation:
The toy car has a spring. When we wind the key of the car, we actually wind the spring. The car now possesses potential energy due to configuration (elastic potential energy). When the car is kept on the ground, it moves as the potential energy get converted into kinetic energy
Answer:
(1) When placed on the ground, it does move.
(2) It gets its energy from the spring's elastic potential energy.
(3) Indeed, the amount of spring windings affects how much energy the toy gains. The toy's spring may store more potential energy when it is wound more tightly.
(4) Test it by winding the toy's spring five times and measuring the distance it travels on the ground. The toy travels a far greater distance after having its spring wound ten times.
In the example above, the object's work causes the energy to be stored. If the energy transmitted to an object is not utilized to change the velocity or speed of the object, it is retained as potential energy.
