Elastic Spring Force
What is Elastic spring force?
A pulling or pushing force exerted on the object that causes it to stretch or compress.
Where can we find this force?
In or between magnets.
What does this force do?
It slows down or stops moving objects in the air.
Complete this phrase about friction, "It occurs between any two surfaces in __________ with each other."
contact
What is the unit of measurement for gravity?
Newton
Choose the odd one? spring---balloon---slime
Slime
True or False: This force is produced even though the magnets are not in contact with each other.
True
What is the direction of the air resistance force when the object is falling from the sky?
Opposite, from the ground upwards.
Which of the other forces is quite similar to this force? Why?
Air Resistance, they both slow down moving objects and they are opposite the movement of the object.
What does this force do?
It pulls down object towards the ground.
What is the direction of this force when an object is being stretched?
Outwards
Complete the phrase " like poles ________________ while unlike poles _____________. "
Repel each other, attract each other.
What factors affect air resistance?
Surface area and shape of the object experiencing air resistance.
True or False: Friction is produced between objects that are not in contact with each other?
False
Who discovered this force? How did he discover it?
Sir Isacc Newton, he got curious when he saw an apple fall down from a tree and so he began to look into it.
The word "deform" in our elastic spring force context mean?
To stretch or compress.
How do we call those invisible lines in between or around the magnet?
Magnetic Field.
Which of the other forces is opposite air resistance? Why?
Gravity, air resistance slows down the fall of an object while gravity pulls it down towards the ground.
Complete this phrase about friction; " The ____________ the surface of an object, the greater the friction produced and the _______________ the surface of an object, the lesser the friction produced."
Rougher, smoother
True or False: Gravity and Weight are the same.
True
Why is this force important?
It allows us to deform things without breaking them and they can return to their original states.
Aside from this force, name some forces that are exerted when objects are in contact with each other.
Elastic spring force and Friction.
Explain how streamline body shape resist air resistance?
Its narrow head and somewhat enlarged body all the way down to its narrow tail enables it to slice through the air, therefore resisting air resistance.
True or False: Friction is also experienced in the water. How?
True, as long as the objects are in contact with each other.
Complete this phrase "all object with _____________ has weight."
Mass
