What is friction?
A force that accelerates the motion of an object.
A force that opposes the motion of an object when it comes into contact with another surface.
A type of energy that is lost during motion.
A force that increases the speed of an object.
How does mass affect the speed of a rolling ball?
Increasing the mass of the ball generally makes it harder to accelerate, affecting its speed.
Mass has no effect on the speed of a rolling ball.
A heavier ball will always roll faster than a lighter ball.
The speed of a rolling ball increases with mass due to greater momentum.
How can you investigate the effect of mass on speed?
By changing the mass of the ball in an experiment while keeping other factors constant.
By measuring the speed of the ball at different heights.
By using a heavier ball to see if it rolls faster on a flat surface.
By increasing the temperature of the ball before the experiment.
What is the difference between contact and non-contact forces?
Contact forces act at a distance, while non-contact forces require physical contact between objects.
Contact forces require physical contact between objects, while non-contact forces act at a distance, like gravity.
Contact forces are stronger than non-contact forces in all situations.
Non-contact forces can only be observed in space.
What is an example of gravity as a non-contact force?
A ball falling from a height demonstrates gravity as a non-contact force.
A person pushing a car demonstrates gravity as a non-contact force.
A magnet attracting a paperclip demonstrates gravity as a non-contact force.
A balloon rising in the air demonstrates gravity as a non-contact force.
What is an example of a contact force?
A book sliding across a table
The gravitational pull of the Earth

The friction between two surfaces in space
What is the role of friction on different surfaces?
Friction is the same on all surfaces, allowing objects to move at the same speed.
Friction varies on different surfaces; for example, a toy car moves slower on a carpet than on a smooth wooden floor due to higher friction on the carpet.
Friction only affects objects that are stationary, not moving ones.
Friction is only present on rough surfaces and has no effect on smooth surfaces.
How does increasing friction affect the motion of a moving object?
It causes the object to speed up.
It has no effect on the object's motion.
Increasing friction causes the object to slow down.
It changes the direction of the object's motion.
Why do objects roll differently on various surfaces?
Because of the varying levels of friction present.
Due to the weight of the objects.
Because of the color of the surfaces.
Due to the shape of the objects.
What happens to a soccer ball when it rolls across grass?
The soccer ball speeds up due to the smooth surface of the grass.
The soccer ball slows down due to the friction between the ball and the grass.
The soccer ball bounces higher because of the grass.
The soccer ball rolls at a constant speed without any change.
What is mass?
The weight of an object measured in pounds.
The amount of matter in an object, usually measured in grams or kilograms.
The volume of an object measured in liters.
The density of an object calculated by its mass and volume.
What is gravity?
A force that pushes objects away from each other.
A force that pulls objects toward each other, such as the Earth pulling objects toward its center.
A type of energy that objects possess due to their mass.
A phenomenon that only occurs in outer space.
What is the effect of gravity on falling objects?
Gravity causes falling objects to decelerate as they approach the ground.
Gravity has no effect on falling objects.
Gravity causes falling objects to accelerate towards the ground.
Gravity causes falling objects to float in the air.
What is air resistance?
A force that propels an object forward in the air.
A force that opposes the motion of an object moving through the air.
A type of friction that occurs on solid surfaces.
A gravitational force acting on objects in the atmosphere.
What is the relationship between friction and motion?
Friction has no effect on motion.
Friction opposes motion, causing objects to slow down or stop.
Friction increases the speed of moving objects.
Friction only affects objects at rest.
What can cause a moving object to increase its speed in a forward direction?
