Physics Quiz for Grade 6

What is the difference between mass and weight?

• Mass is the force exerted on an object due to gravity, while weight is the amount of matter in an object.

• Mass is the amount of matter in an object, while weight is the force exerted on an object due to gravity.

• Mass and weight are the same thing and can be used interchangeably.

• Mass is measured in pounds, while weight is measured in kilograms.

How does gravity affect sinking and floating?

• Gravity pushes objects away from the center of the Earth

• Gravity has no effect on sinking or floating

• Gravity pulls objects towards the center of the Earth, affecting their ability to sink or float.

• Objects sink or float based on their color

What is friction and how does it affect motion?

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

• Friction is the force that helps to increase the speed of an object in motion.

• Friction is the force that has no effect on the motion of an object.

• Friction is the force that only affects the motion of objects in water.

Explain the effect of forces on an object's motion.

• Forces can cause an object to start moving, stop moving, or change direction and speed.

• Forces have no effect on an object's motion

• Forces can make an object disappear

• Forces only affect an object's color

How is mass different from weight?

• Mass is the amount of matter in an object, while weight is the force exerted on an object due to gravity.

• Mass is the measure of how heavy an object is, while weight is the measure of how much space an object takes up.

• Mass and weight are the same thing and can be used interchangeably.

• Mass is the force exerted on an object due to gravity, while weight is the amount of matter in an object.

Why do objects sink or float in water?

• Due to the temperature of the water

• Because of the color of the object

• Depending on the shape of the object

• Based on their density and the density of the water

What are the different types of friction?

• Static friction, kinetic friction, rolling friction, and fluid friction

• Hard friction, soft friction, solid friction, and liquid friction

• Fast friction, slow friction, medium friction, and high friction

• Smooth friction, rough friction, bumpy friction, and sharp friction

How does friction affect the movement of objects?

• Friction causes objects to move without any resistance

• Friction has no effect on the movement of objects

• Friction increases the speed of objects

• Friction creates resistance to the movement of objects.

Why do we weigh less on the moon than on Earth?

• Due to lower gravity on the moon

• Because the moon has stronger gravity

• Because the moon is closer to the sun

• Because the moon is made of cheese

What is the relationship between gravity and sinking?

• Gravity pulls objects down, causing them to sink.

• Gravity pushes objects up, causing them to sink.

• Sinking is caused by air pressure, not gravity.

• Gravity has no effect on sinking.
