EOG Prep: Force and Motion 5th Grade NC.5.P.1

Front

What are balanced forces?

Back

Balanced forces are forces acting on an object that are equal in size but opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal and opposite, causing a change in the motion of an object.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other, such as the force that pulls objects toward the Earth.

Front

How do unbalanced forces affect motion?

Back

Unbalanced forces can change the speed and direction of an object, and can cause an object at rest to start moving.

Front

What is mass?

Back

Mass is the amount of matter in an object, which affects how much force is needed to move it.

Front

How does mass affect motion?

Back

The greater the mass of an object, the greater the force needed to move it.

Front

What is friction?

Back

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

Front

What is the force of motion?

Back

The force of motion refers to the push or pull that causes an object to move or change its position.

Front

What is an example of balanced forces in everyday life?

Back

An example of balanced forces is a book resting on a table; the force of gravity pulling it down is balanced by the table pushing it up.

Front

What happens to an object at rest when unbalanced forces act on it?

Back

An object at rest will start to move when unbalanced forces act on it.
