Gravity Quiz for KS3 Physics Students

What is gravity?

• A form of light

• A type of energy

• A force that pulls objects with mass towards each other

• A type of sound wave

What keeps the planets in orbit around the Sun?

• Magnetism

• Gravity

• Electricity

• Wind

What happens to an object as it falls towards Earth?

• It gets faster

• It moves sideways

• It stays at the same speed

• It slows down

What is air resistance?

• A force that speeds up objects

• A force that acts in the same direction as movement

• A force that acts in the opposite direction to movement

• A force that has no effect on moving objects

Why does a feather fall slowly to the ground?

• It is heavy

• It is magnetic

• It has a large surface area

• It is made of metal

What happens when a skydiver opens their parachute?

• Their speed increases

• Air resistance decreases

• Their surface area decreases

• Air resistance increases

What is mass?

• A measure of the color of an object

• A measure of the temperature of an object

• A measure of the speed of an object

• A measure of the amount of matter in an object

What is the relationship between mass and gravitational force?

• Mass only affects gravitational force in space

• Greater mass means stronger gravitational force

• Greater mass means weaker gravitational force

• Mass has no effect on gravitational force

What is the effect of distance on gravitational force?

• Closer objects have stronger gravitational force

• Distance has no effect on gravitational force

• Gravitational force only works at long distances

• Closer objects have weaker gravitational force

Why is it difficult to measure the gravitational pull of small objects?

• Because they are too close together

• Because they are not big enough

• Because they are not heavy enough

• Because they are too far apart
