Give five effects of force.

Here are the answers to your questions:

1) Differentiate between Contact and Field forces and give two types for each.

• Contact forces are forces that act on an object only when there is direct physical contact between the interacting objects.
  • Two types of contact forces are:
    1. Friction: A force that opposes motion between surfaces in contact.
    2. Normal force: The support force exerted by a surface on an object resting on it.
• Field forces (also known as non-contact forces) are forces that act on an object without the need for direct physical contact. They act through a field.
  • Two types of field forces are:
    1. Gravitational force: The attractive force between any two objects with mass.
    2. Electromagnetic force: The force between electrically charged particles or magnetic poles.

2) Give five effects of force.

Five effects of force are:

1. A force can change the state of motion of an object (e.g., start a stationary object moving, stop a moving object, or change its speed).
2. A force can change the direction of motion of an object.
3. A force can change the shape or size of an object (deformation).
4. A force can cause an object to rotate or turn.
5. A force can cause pressure when applied over an area.
