What is energy transfer in waves?

Back

Energy transfer in waves refers to the movement of energy from one place to another through a medium (like air, water, or solid materials) without the physical movement of the medium itself.

Front

What are the two main types of waves?

Back

The two main types of waves are mechanical waves (which require a medium, like sound waves) and electromagnetic waves (which do not require a medium, like light waves).

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when two forces acting on an object are not equal, causing the object to accelerate in the direction of the greater force.

Front

How does distance affect gravitational force?

Back

Gravitational force decreases as the distance between two objects increases, according to the law of universal gravitation.

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined.

Front

What is an example of a force pair?

Back

An example of a force pair is when a person pushes against a wall; the wall pushes back with an equal and opposite force.

Front

What happens to an object when forces are balanced?

Back

When forces are balanced, the object remains at rest or continues to move at a constant velocity.

Front

What happens to an object when forces are unbalanced?

Back

When forces are unbalanced, the object will accelerate in the direction of the net force.

Front

What is the relationship between force and motion?

Back

Force is a push or pull that can cause an object to start moving, stop moving, or change direction.
