Force and Motion grade 5

Front

What is force?

Back

A push or pull on an object that can cause it to move, stop, or change direction.

Front

What is motion?

Back

The change in position of an object over time.

Front

What is mass?

Back

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

Front

What is friction?

Back

A force that opposes the motion of an object when it comes into contact with another surface.

Front

What are balanced forces?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Forces that are not equal, causing a change in motion of an object.

Front

How does mass affect the force needed to move an object?

Back

Greater mass requires more force to move the object.

Front

What is the effect of adding water to a surface when moving an object?

Back

It reduces friction, making it easier to move the object.

Front

What is the relationship between force and motion?

Back

Force causes motion; without force, an object at rest stays at rest.

Front

What is an example of a situation with balanced forces?

Back

A book resting on a table, where the force of gravity is balanced by the support force from the table.
