A)Gravity is a pulling force. The more weight something has, the greater the force of gravity it has. That means really big objects like the earth has everything attract to it.
B) The force of gravity 100 kilometres above Earth is just 3% less than on the Earth’s surface
c) Dropping the football onto your foot, an apple dropping from an apple tree. From experiment 1: dropping a tennis ball
D)
A) Friction is a force when you rub something against another thing causing it to move, stop moving or heat up.
B) There are 3 different types of friction: Dry Friction,Fluid Friction and Rolling Friction.
c) Rubbing your hands together, creating warmth and stopping your bike. From experiment 1: Rolling a ball down a ramp and rolling a ball with a straw.
D)
A) Push is a force that move one object away from the direction it got forced from. Push works with different forces like friction
B) You do around 20-30 push forces a day depending on what you are doing.
C)Pushing a door open, pushing a swing and pushing a pram. From experiment 1:using a straw blowing into glass.
D)
A)Normal is the force that keeps us up right and balanced. without it we could not stand up right.
E) I noticed that my planets only orbit because I made it start with an angle.
E) I noticed that the arrows on diagrams don't just show direction, but they can also show how strong the force is. I also noticed that there are lots of mechanical machines that uses the force push.
A) Magnetism is a force that either attracts two different magnetic materials or repels a magnet from another magnet.there are 4 main different materials that have the magnetic force in them; steel, iron, nickel and cobalt. there is a north pole and a south pole in every magnet.
B) Earth is like one big magnet; the earth has nickel and iron in it, two magnetic materials.
two magnets attracting, when you stick a magnet on the fridge.
Electrostatic is the force of electricity. this force works with multiple forces but mostly friction.
There are three different types of electrostatic energy; charging, induction and conduction.
c) rubbing a balloon against your head, lightning
B) you mostly see normal force on objects that are horizontal.
C) The opposite force to the normal force can only be gravity.
D)
A) pull is a force that move one object away from the direction it got forced from. Push works with different forces but mostly push.
A) A twist is a turn in the opposite direction from another; coil or spin twists forms into a bent, curling, or distorted shape
B)Pulling is making use of another force as well as pressure, which is force applied by an amount of weight.
C) pulling a door open, pull sheets off a bed, pulling bin out of its place.
D)
E) I noticed that pull can also be a non contact force as well as a contact force.
B) Twist force is also known as torsion
C) turning a handle, twisting a jar open,twisting a rubix cube.
D)
E) I noticed that there are more examples of twist every day life than people think.
