Basic Physics Concepts Quiz

What is a collision?

• When two objects hit each other

• When one object moves by itself

• When objects are just near each other

• When two objects come close but don’t touch

What is a contact force?

• A push or pull when objects touch

• A force acting at a distance (like magnetism)

• A force that only happens in space

• A force that makes objects disappear

What is deformation?

• A change in shape when force is applied

• A scratch or mark left on a surface

• A change in color of an object

• A movement without touching anything

What is the breaking point of a material?

• The force amount where it can no longer return to its original shape

• The first moment an object starts to bend

• The time it takes for something to fall

• The place where two objects meet

What is elasticity?

• The ability of a material to return to its original shape after being deformed

• The ability to resist breaking no matter what

• The ability to stick to other objects

• The ability to stretch forever

What is nonelastic deformation?

• A permanent change in shape

• A temporary bend that goes back after force is removed

• A reversible color change

• A change in speed of the object

In science, what is a system?

• A set of objects interacting together

• A single object moving on its own

• A machine that runs on electricity

• A random group of items with no connection

What is a model?

• A representation to explain or predict phenomena

• An exact replica of the real thing

• A type of collision

• A rule about how objects must behave

What is a force pair?

• Equal and opposite forces two objects apply to each other

• Two forces pushing in the same direction

• A single object moving on its own

• A force without direction

What is a free-body diagram?

• A diagram showing all the forces acting on an object

• A picture of the object without any labels

• A timeline of the object’s motion

• A graph of speed vs. time
