Force and Motion

Front

What is force?

Back

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

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is friction?

Back

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

Front

What factors affect the distance an object moves when pushed?

Back

The mass of the object and the amount of friction between the object and the surface.

Front

What happens to an object's motion when a greater force is applied?

Back

The object will accelerate and move faster.

Front

What is the relationship between mass and force?

Back

Heavier objects require more force to move the same distance as lighter objects.

Front

What is a variable in an experiment?

Back

A variable is any factor that can change in an experiment, affecting the outcome.

Front

Why is it important to test one variable at a time in an experiment?

Back

Testing one variable at a time allows for clearer interpretation of results.

Front

What is the effect of a rough surface on friction?

Back

A rough surface increases friction, making it harder for objects to slide over it.

Front

What is the effect of a smooth surface on friction?

Back

A smooth surface decreases friction, allowing objects to slide more easily.
