Force
Is either a push or pulling movement.
What is a force?
forces that occur when two objects physically touch each other.
What is a Contact Force.
what are forces that act inside an object?
What is a Internal Force.
What is the force that opposes the motion of objects and when they are in contact with each other?
What is Friction.
What type of force causes parts of an object to slide past each other in opposite directions.
What is Shear Force.
When you push a toy car what force are you using?
what is a pushing force.
This type of Force dosesnt require physical contact between objects. They can act over a distance.
What is a Non-Contact Force.
What are 4 types of internal forces?
Shear, Tenison, Torsion, Compression.
What is Friction.
What force causes an object to twist around its length.
Torsion.
Forces can make things (4 things)
Kicking a soccer ball is what kind of force
Push and Contact force
Name 3 types of External Forces that can happen on an object.
Applied force, friction, and elastic/spring force.
What is the force exerted by an elastic object, like a spring or a stretched rubber band, when it is compressed or stretched.
What is Elastic or Spring Force.
what is a property of materials that allows them to change shape permanently.
Plasticity. Give an example.
pushes or pulls that come from outside an object.
What is an external force
An apple falling from a tree is what kind of force?
what force is a push or pull that is directly put on an object by a person or another object.
What is applied force.
What force stretches something.
Tension, it is a pulling force.
What is a property that allows materials to return to their original shape after being stretched or compressed.
What is Elasticity.
External forces can be characterized into 2 types of forces.
Contact forces and Non-Contact force
A paper clip being moved by a magne. Is what kind of force.
Magnetic Pull and Non-Contact Force
Pushing a shopping cart is creating: friction,applied force, or elastic/spring force.
Applied Force
what force is the opposite of Tension. This force squashes or pushes something together.
what is Compression.
How do internal and external forces work together? How are they related? Give and example.
You can not have an External force without an internal force happening aswell.
