2. Why do we get hurt when we come in front of a moving bicycle?
3. What happens when a rubber band is stretched?
4. Name five different forms of ener


Explain the following terms.
1. Energy
2. Magnetic energy
3. sound energy
4. work
5. Chemical energy ​

Answer 1

Fertilization can be defined as the union of two haploid gametes, the spermatozoa and the oocyte, hereto referred to as egg, to restore the diploid state, form a zygote through the process of egg activation, and commence a series of mitotic divisions that results in cell differentiation and embryo development.

Answer 2

1. Gravitational energy or gravitational potential energy is the potential energy a massive energy has a relation to another massive object due to gravity
2. Impulsive force is equal to

F=I/delta T

As the time of impact is very less, the Impulsive force is very large and we get hurt when we come in front of a moving bicycle

3 . A rubber band is an elastic material in nature. When stretched, it changes its shape and when the applied force is removed, it retains its original shape. That is why the rubber band change it's shape event though it is solid Also, if the force applied is excessive the rubber band would break

4. Chemical energy

Nuclear energy

Electrical energy

Sound energy

Gravitational energy

1. Energy is the capacity to do work. Energy is transfered from one body to another
2. Magnetic energy is the energy form of moving charges (electrons)
3. Sound energy is the movement of energy through a substance, such as air and water in the form of waves. It is produced when a force creates an object or substance to vibrate
4. Work is the energy transferred to or from an object through the application of force along the displacement
5. Chemical energy is the energy stored in the chemical compounds. The chemical energy in a battery can also supply electrical power by means of electrolysis
