4. What is the direction of force of friction acting on a moving object?
3. Which type of surfaces produce (a) leasi friction, and (b) too much friction
5. Name a device which is used to measure force acting on an object.
6. What is a spring balance ?
7. Out of sliding friction, static friction and rolling friction :
(a) which one is the smallest ?
(b) which one is the large​

Answer 1

Answer:

1 Frictional force

2.because that which apply force for movement, is switched off

3.a,plain surface,,b. rough surfaces

4.opposite

5.spring balance

6.A spring scale or spring balance or newton meter is a type of mechanical force ... It works by Hooke's Law, which states that the force needed to extend a spring is proportional to the distance that spring is extended from its rest position.

7.a,rolling b, static
