Forces Flashcard

Front

What is a force?

Back

A force is a push or pull that can change the motion of an object.

Front

What are balanced forces?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are not equal and can cause an object to start moving, stop moving, or change direction.

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces in contact.

Front

What is gravity?

Back

Gravity is the force that pulls objects toward each other, such as the Earth pulling us down.

Front

What is the 'domino effect'?

Back

The domino effect is when one event causes a chain reaction of similar events, like falling dominoes.

Front

What is the role of friction in motion?

Back

Friction can slow down or stop the motion of an object, depending on the surfaces in contact.

Front

What is a testable question?

Back

A testable question is one that can be answered through experimentation and observation.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
