Investigate Two Factors That Affect The Distance Taken For A Toy Car To Stop After Rolling Down A Ramp?

According to Newton's 2nd law, the more mass an object has, the more acceleration it will gain as it moves and the more speed there is. This means that it will travel for longer if it has more mass because its weight will cause the object to gain more acceleration. The lighter an object is, the less acceleration is built up as it goes down a slope and so it will stop quicker. Less acceleration means less speed and more resistance to the object.

If a heavy toy car is used it will take longer to build up momentum as it travels down a ramp but it takes longer to stop as it as it has build up a lot of speed by this stage.If a lighter car is used it will pick up momentum quicker but will stop sooner after rolling down the ramp as it will not have build up as much speed as the heavier car.

Air resistance against the car as it travels and the friction of the wheels against the ground slows it down and so reduces the toy car's potential travelling distance

The weight of the car\on the car, the slope of the ramp and the material the car lands on or on the ramp

At the top of the ramp the toy has a certain amount of potential energy. The amount of this energy depends on the height of the ramp and the weight of the toy. (The toy's weight is dependent on its mass and the force of gravity.) As the toy rolls down the ramp this potential energy is converted to two other types of energy: Kinetic energy and heat energy. The amount of heat energy depends on friction and air resistance. The lower the total resistance the more kinetic energy, and the more speed, the toy has at the bottom of the ramp.

The time taken for the toy to stop depends on its kinetic energy at the bottom of the ramp and the same sources of resistance as before. The lower the total resistance the more slowly the kinetic energy is turned into heat energy and the longer the toy takes to stop.

A toy car at the top of a ramp has a certain amount of potential energy, by virtue of its position.  As it rolls down the ramp, its potential energy is transformed into kinetic energy.  After the toy car reaches the bottom of the ramp and is rolling along a flat surface, it is expending its kinetic energy.  The greater the friction between the toy car's wheels and its axles, the faster the accumulated kinetic energy will be expended and the shorter the distance that the toy car will travel.

You need to test 5 different surfaces and change the height of the ramp

The heaver it is the fastest it will stop the lighter it is and the highest the slope gets the furthest it goes =] Doing your Junior cert ha me to =]

Different surfaces and weight on the car also the angle at which the ramp is at!!!!

Newtons 2nd law states that the applied force equals the mass times the acceleration. As the mass increases the force increases by the same constant so the acceleration will remain the same regardless of mass :)

The angel of the ramp
Surface of the ramp
Length of slope
Momentum/ speed / mass of toy car / Friction...
...hope it helps?!!...

Yep, it's slope and surface. Use things like carpet and sandpaper to slow the car down after it goes off the ramp.

The factors that affect this are
1. The surface of the the ramp can speed up of slower the car down the ramp.
2. The type of car (big or small)
3. Hight of the ramp.

The surface of the ramp the sloe and the lenght are factors that effect the stopping  distance of a toy car rolling down a ramp.

Forces (slow it down or change direction )
friction (between air and the surface )
gravity (pulls a vehicle down a slope )
the steepness and length of the slope
speed the toy car was travelling
the car's mass
terrain or surface of the slope
... I think ?!

We got this title for the jc today also :S confused ..I think its height and surface though ...

Slope and surface

It all depends on which priest says mass and how long the sermon.

Its the slope and friction

The height of the ramp
the weight of the car
friction!!!

Ok I'm absolutly crap at this kind of thing and I just got it as my JC title....
Can anybody tell me, in a language I might understand, what I have to do?
Please, I would be sooo grateful..
Xx

Gravity and friction!!!!! The surface on the ground will slow the car down!!!

This question is part of the Junior cert 2010 science project

Angle,surface and weight of the car

I'm doing this project too you

Gravity

This is stupid!

The surface it comes on to.

Put glue on the end of the ramp or traffic lights

The size of the car
the height of the ramp

If the surface is lubricated the car will travel a further distance than if their is lots of friction from the rock i.e rocks. The height of the ramp also affects the distance it will travel.

Drop in ta second, let de booth down around de corner, go ripen down ta Brockhagen...n Das how you drive a hot wheel car

Thanks, I have a exam next... And hopefully this is about it  :DD!!

Force friction gravity lubrication of the ramp before hand the type of surface height and angle of the ramp all contribute to this answer
I hope this has helped as I am also doing this as my project :)

It rolls down at high speed causing the engine to lock in a high rpm

Put the car on a bumpy road and push it down a cows back then use the cows milk to lubricate the surface :) hope this helps!

Hi guys my name is julio just wondering is anyone free on saturfay ...only joking need answers now

The weight of car / friction / gravity / the slope of ramp / the surface of the ground it lands on... JOHN POTTER JOHNY JOHNY POTTER HY-UP you BOIIYA JOHN

Are you doing this as your science experiment thing for JC?
I got the same thing.but I'm sooo confused I have no clue where to start..but probably slop is one of them..nd surface probably?
You know wen you hav those 2 what do you do then??
