Push
-
D. Pictures:
-
E. Observations:
- Just about any object, can be pushed, e.g. a door, a laptop, a glass of water.
- A push is always a contact force, because to push something you must make contact with it.
- The amount of force you apply when swinging the bat (how hard you hit the ball), and the mass of the ball.
A. Explanation: To apply a force on someone or something, causing it / them move away from oneself.
Twist
-
D. Pictures:
-
E. Observation:
- Any object that doesn't hold it's shape e.g. slime, clay, plasticine.
- Yes, if the push force is strong enough that it makes the object twist.
- Because it is technically a push and pull.
A. Explanation: To hold two ends of an object, pulling and rotating each end in opposite directions.
Pull
-
D. Pictures:
B. Facts: The harder you pull, the faster something moves.
E. Observation:
- A pull is always a contact force, because to pull something you must make contact with it.
- Almost any object can be pulled, e.g. a drink bottle, a book, a lamp.
- You can not convert a push force into a pull force because they are opposite forces.
A. Explanation: To apply force to someone or something, causing it / them to move towards oneself.
Friction
B. Facts: Friction in a fluid is called viscosity. Viscosity is how hard it is for the fluid to flow / move. E.g. Honey is more "viscous" than water.
D. Pictures:
-
A. Explantion: The resistance that one object or surface encounters when it moves over another surface.
Non-Contact
Electrostatic
-
B. Facts: Rubbing two materials / objects can result in something called charge. Charge is something being moved from one surface to another.
D. Pictures:
C. Example: When you rub a balloon on your hair and slowly pull it away from your head, the hair will be pulled towards the balloon.
Gravity
-
E. Observation:
- When a planet is further away from the sun it is colder and darker, if a planet is closer it is hotter and lighter.
B. Facts: Tides are caused by the rotation of the Earth and the gravitational effects of the Moon and Sun.
D. Pictures:
C. Example: When apple falls from a tree because of gravity, it is actually being pulled not falling.
