A student strikes a block at the bottom of a ramp, giving it an initial speed vo up the ramp, as shown at right. There is friction between the ramp and the block as it slides a distance x up the ramp and then slides back down. On the dots below, which represent the block as it is sliding up the ramp and down the ramp, draw and label

the forces (not components) exerted on the block. Represent each force by a distinct arrow starting on, and

pointing away from, the dot. The dashed lines are drawn at the same angle as the surface of the ramp.


Up the Ramp


Down the Ramp

Newton's second law allows to find the results for the free body diagram of the movements on the ramp are;

  • In the attachments we have the graphs of the forces for the case of raising and lowering the ramp.

Newton's second law indicates that the net force is proportional to the product of the body's mass and its acceleration.

A free-body diagram is a schema of the force where the details of the bodies are omitted.

Reference systems are coordinate systems with respect to which measurements and vector decompositions will be carried out.

In the attachments the part of going up the ramp the x axis is parallel and the positive direction in the direction of movement:

  • Raising the positive x-axis ramp up
  • Going down the ramp positive x axis going ramp down.

The positive direction of the y-axis is perpendicular to the ramp.

We can see that the force of the weight and the normal remain fixed in any of the movements, but the friction force that opposes the movement changes direction.

In conclusion using Newton's second law we can find the results for the free body diagram of the movements on the ramp are;

  • In the attachments we have the graphs of the forces for the case of raising and lowering the ramp.
