How to change the speed and the direction of a moving body?

What are the efftects of force?




please help me. by answering these question

Answer 1

Answer:

Electrostatic forces are non-contact forces; they pull or push on objects without touching them. Rubbing some materials together can result in something called 'charge' being moved from one surface to the other. Charged objects pull on other uncharged objects and may either push or pull on other charged objects.

Answer 2

Explanation:

1. It's attractive or repulsive force between two electrically charged objects. Electrostatic forces are non-contact forces; they pull or push on objects without touching them. Rubbing some materials together can result in something called 'charge' being moved from one surface to the other. Charged objects pull on other uncharged objects and may either push or pull on other charged objects.
2. wheels of buses and trucks are heavier than the wheels of cars or scooters because the buses and trucks are heavy and require to exert less pressure. The scooters and cars have less wide wheels because they are lighter in weight and need more pressure for gripping.
3. Muscular force is a type of force which acts after contact.example : Walking, running, weightlifting, kicking a ball etc.
4. first is:- Your clothes bend with your body under the forces applied. Another examples of forces that cause a change in the shape of an object are as follows: (i)Squeezing of a plastic bottle changes the shape of the bottle. (ii) Deformation of clay by pressing it between the hands.
5. By Applying suitable Force On That Moving Body in particular direction.
6. 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.
