There are two types of forces
1. Physical force : in this type of forces we require direct contact between two bodies
2. Field force: here we do not requires any type of physical contact with the body
so here in this type of field force we do not required any contact but only due to field present near it the body can move
so here several examples are there
a) when a magnet is placed near a piece of iron then it will move towards the iron
b) a positively charged particle when come near another charged particle then it will get attracted or repelled.
so as per all above discussion we can say that an object can move without any direct contact
Explanation:
Animas and plants react to stimuli which may come from other living things or from the environment. A stimulus causes the organism which receivs it to respond to it. Therefore the stimulus changes the behavior in the organism in some way.
Fossil Fuels is the largest source for energy
