Question

1
E. Differentiate between the following:
Contact force and force at a distance
2. Force and pressure
3. Frictional force and magnetic force​

Answer 1

Answer:

1. Contact forces involve push . Contact forces involve push, pull and friction. ... At a distance At a distance force is when two interacting force is when two interacting objects are not touching, for example: the moon and the Earth's seas. At a distance forces encompasses gravity and magnetism.

2. A force can be a push or a pull. When a force is exerted on an object it can change the object's speed, direction of movement or shape. Pressure is a measure of how much force is acting upon an area. ... Therefore, a force acting over a smaller area will create more pressure.

3. Frictional force is a contact force , it can act only when two bodies are in contact. Magnetic force is a non contact force and can act even when two bodies are not in contact. ... Magnetic force attracts or repels two bodies.
