Ramps

Question 0

Newton’s 3rd Law of Motion

Answer 0

For every force object (i) exerts on (ii)

there’s an equal but oppositely directed force object (ii) exerts on (i).

Question 1

Support Forces

Answer 1

Forces preventing 2 surfaces occupying same space same time

- exerted perpendicular to those surfaces

Question 2

Downhill Force 2 sources

Answer 2

1) Weight of object (gravity on wagon)

2) Support Force (ramp on wagon)

Question 3

Horizontal surface = _____ support forces

Answer 3

Vertical

Question 4

1) Object on flat surface ramp force =? &

2) Tilted ramp force=?

Answer 4

1) 0

2) Increased ramp force & decreased support force

Question 5

The steeper the slope____

Answer 5

The higher downhill ramp force

Question 6

Uphill force you exert on wagon equivalent downhill force on wagon,

How will wagon move?

Answer 6

Wagon move constant velocity, may be 0.

Question 7

Energy

Answer 7

The capacity to do work,

More exhausting give away vs receive energy

Question 8

Conserved Physical Quantity

Answer 8

Can’t create/destroy it, only move from object -> object

Question 9

Work

Answer 9

The mechanical means of transferring energy
- = force• distance (in direction of force)

• horizontal motion doesn’t matter,
  Only vertical: Increased elevation/altitude

Question 10

To do work (2) on object

Answer 10

1) have to push/pull on object
2) object must move a distance
(In direction push/pull)

Question 11

2 forms of energy

Answer 11

Kinetic- energy associated w/ motion

Potential- energy stored in forces
Ex. Gravitational, elastic, magnetic, electrostatic, nuclear & chemical potential energy.
(Individual types energy not conserved, total energy IS)

Question 12

You transfer energy as you ___ an object.

You receive energy as you ___ an object

Answer 12

Lift
Receive
- More exhausting give away vs receive energy

Question 13

Conserved Physical Quantity

Answer 13

Can’t create/destroy it; only moves from object -> object.

Question 14

The higher altitude lifted object = higher ______

Answer 14

Gravitational Potential Energy

Question 15

The mechanical advantage pulling up/falling down ramp?

Answer 15

Ramp allows you rearrange amount & direction of force needed to do same activity (on flat surface)

Question 16

Work Your doing lifting object=?

Answer 16

Objects weight • upward distance it moves.

- Becomes GPE in object.

Question 17

Gravitational Potential Energy = ?

Answer 17

Weight• Altitude
- 0 GPE= 10 N • 1m

.•. GPE = 10 Nmeters (joules)
