What is the resultant force and its direction?

Friction is a ..............................force a-contact b- noncontact

Factors affect the friction force.  a-type of surfaces   b-The weight c-both

The bigger the arrow, the smaller the forces. True or false.

heavy objects can give low friction. (TRUE or FALSE)

which produces greater friction .............. a-Rougher surfaces b-smooth surfaces.

The unit of force is ........................

........................ Is a force that works against of a moving object.

What is the resultant force and what is the direction?

True or Fales: Friction can make things slow down or stop.

We use an arrow to measure the direction and magnitude. (True or False)

When most objects with smooth surfaces rub, there is less friction. (True or False)

Friction is a force that acts in an ___________ direction of movement. a-similar b-opposite

What is the direction of the force in this image?

If a contact surface is rough, the friction is high. (TRUE or FALSE)
