Force and Motion STAAR Review

Front

What is the importance of testing one variable at a time in an experimental investigation?

Back

It allows the experimenter to correctly and more easily interpret the results of the experiment.

Front

What question does an investigation using a spring scale to pull shoes across a table aim to answer?

Back

How does the type of shoe affect the amount of force required to pull it?

Front

Why is it important to conduct multiple trials in an experimental investigation?

Back

Repeated investigations make the results more reliable.

Front

What causes different distances moved by boxes when pushed with the same amount of force?

Back

Heavier objects have increased friction with the floor.

Front

What is friction?

Back

Friction is the force between two objects when they come into contact with each other.

Front

What type of surface increases friction when an object moves against it?

Back

A rough surface.

Front

Define force in the context of motion.

Back

Force is a push or pull on an object that can cause it to accelerate.

Front

What is the relationship between mass and force in motion?

Back

Greater mass requires more force to achieve the same acceleration.

Front

How does friction affect the motion of an object?

Back

Friction opposes the motion of an object, slowing it down or preventing it from moving.

Front

What is the role of gravity in force and motion?

Back

Gravity is a force that pulls objects toward each other, affecting their motion.
