Exploring the Basics of Forces

What instrument is used to measure the amount of force applied to an object?

• Caliper

• Spring scale

• Barometer

• Thermometer

What effect does gravity have on a falling apple?

• It changes its direction

• It makes it float

• It speeds it up

• It slows it down

What happens when forces are applied in opposite directions?

• They make movement easier

• They make the object float

• They cancel each other

• They have no effect

What is the result when two forces pull from different angles?

• The object splits

• The object moves at an angle

• The object does not move

• The object moves in a straight line

What causes friction when objects slide past each other?

• Magnetism

• Gravity

• Electrical forces

• Mutual contact force

What force is responsible for keeping a block floating on water?

• Magnetic force

• Friction

• Buoyant force

• Elastic force

What does the force of gravity do to an object on a table?

• Has no effect

Which materials are typically attracted to magnets?

• Rubber and cloth

• Iron and steel

• Wood and paper

How do two magnets interact when their same poles are near each other?

• They repel

• They attract

• They become neutral

• They explode

What happens when a north pole and a south pole of two magnets are brought together?

• They demagnetize each other

• They create an electric current

• They attract each other

• They repel each other
