Mechanics - Forces on Slopes

Flashcards

What is the angle beneath the red block?

\[3\text{kg}\]

What is the resultant force in this diagram, assuming no resistive forces?

\[3g\sin(30^\circ)\]

What is the resultant force in this diagram?

\[2g\sin(20^\circ) - 2\]

What is the resultant force in this diagram?

\[5g\cos(60^\circ) - mg\sin(30^\circ)\]

What will happen to the direction of friction for an object moving up a slope but accelerating downwards?

It will flip direction when the object flips direction.
