Okay, so this one we have a block that is sliding down a ramp at a constant velocity.
00:08
Now, which of the given diagrams correctly depicts the forces on the block.
00:11
Okay, let us draw our own free body diagram.
00:24
Okay, suppose this is the rump, this is the angle that the ramp makes with the horizontal, let's know that as data.
00:36
Suppose this is the block, suppose it's the center of gravity of the block, pulling it downwards, particularly downwards is the gravitation force or its weight and perpendicular to the surface of the ramp is the normal force.
01:06
Okay, since the black is sliding down a ramp, then the friction force is acting opposite its motion.
01:16
So in this direction.
01:22
Okay, opposite to normal force is the component of weight for the gravitational force.
01:31
This plane...
