Force and Gravity
When cars come downhill gravity pulls the car/objects down.
When you push a car uphill gravity pulls the car back down.
If the car is on flat ground the car just goes normal but doesn't move very far.
Gravity is a force that pulls objects towards the center of the earth.
The car that moves the farthest is the car going down hill and the car that moves the least far is the car going uphill because the car moving downhill has more force.
It is easier to push a car downhill than uphill.

Force of gravity
When a car goes down hill it moves faster than a car going up hill.
When a car goes up hill it goes a bit slower than going down hill .
When the car goes down hill gravity is pulling it toward the center of the earth.
When a car is going up hill gravity is pulling it back so it goes slower.
It doesn't need much force to go down a hill it moves by itself.
It needs the most force to go up hill.
On flat land it doesn't move very far with a small push.
Gravity is a force that pulls objects towards the center of the earth.
Cars can go faster down hill than up hill because up hill you need lots of force to move it.
The car going up hill needs the most force.

Force and Gravity
When cars go down hill they have more force than cars going up hill because it has more weight going down hill. A car going down hill moves really fast and doesn't need much force because its going down hill. Cars need lots of force to go up hill because gravity is pulling them back down and it wants to go up instead.
When you drop something the gravity pulls it towards the center of the earth or the ground so what goes up has to come down. It falls down without a push or pull.

Gravity
When we jump up we always come down again. This is because of a force called gravity. Gravity pulls things back towards earth. Gravity pulls the parachute down to earth. Gravity affects everybody and everything in the world. Watering a plant, playing basketball, a cheetah running, a dancer jumping and a waterfall.

Force Work and Energy
I know that a force is a push or a pull and heavy objects need more force to move than lighter things. What goes up must come down you need more force to stop a heavy object than a lighter object. Gravity is weaker on the moon than on earth. A rocket needs more force to lift off into out of space.

Gravity, Force and Work
What goes up must come down.
Force is pulling and pushing.
Force can stop things.
Force is able to move things.
You can stall energy.
All things need energy to move.
For example you can get:
*Electrical energy comes from power.
*Heat energy comes from fires.
*Muscular energy comes from work.
*Solar energy comes from the sun.
*Hyde energy comes from water .
*Wind energy comes from wind mills.
You can only move things with force.
Gravity pulls things towards the center of the earth.
To stay connected to things .
You can stay to the floor .
You can't breath in space .
The moons gravity is lighter than on earth.
Gravity effects everything .
Things feel lighter on the moon.
Some forces can push and pull objects with out even touching them. .

Force, Work and Energy
Force is pushing and pulling things.
Force can change direction.
All things have energy to more electric energy.
Solar energy
Wind energy.
Heavy objects take more force to stop once they start moving.
I know that a force is a push or pull.
Heavy things need more force to move than lighter things.
A bigger force will move an object further than a
weaker force.
What goes up must come down because everything is pulled towards the center of earth its called gravity.
