Forces and Collisions Flashcards
Speed
the rate at which someone or something is able to move or operate.
Mass
the amount of matter in a particle or an object
Force
A push or a pull
Contact Force
A push of pull between objects that touch
Newton
A unit of measurement for force
Deformation
A change in shape
Elastic Limit push back
Amount of force an object can take and still return to its original shape
Breaking Point
The amount of force it takes for an object to break (permanent damage)
Kinetic Energy
A form of energy that an object or a particle has by reason of its motion
Friction
the force that resists motion when the surface of one object comes in contact with the surface of another.
Air Resistance
the force that acts in the opposite direction to an object moving through the air
Do all objects bend when a force is applied to them? Why?
All solid objects deform elastically when force is applied to them up to a point
What factors affect the elastic limit of an object?
Pressure and length
When two objects are in contact with each other, what happens? How do the forces compare?
Objects in contact exert forces on each other (friction, elastic pushes and pulls) both objects experience forces that are equal in magnitude and opposite in direction.
What is the relationship between mass and kinetic energy?
Kinetic energy is directly proportional to the mass of the object
