What is a force? Check all the correct answers.
It is a pull or a push.
It can change an object's position or put it in motion.
It can slow down objects and make them stop.
What is a contact force?
It is a force that can only act between objects that are touching.
It is a force that can act between objects at a distance.
It is a force that does not exist between objects.
Which of the pictures below shows a contact force? Check all correct answers.
Which picture below shows a noncontact force?
What is friction?
It is the force that pulls objects towards the center of Earth.
It is the force that occurs when two objects rub against each other.
It is the force of attraction between certain materials.
Which picture below is an example of friction?
Why is it harder for the boy in picture B to get down the hill?
In picture B, the grass is smooth and so there is less friction taking place between the boy and the grass.
In picture B, the grass is rough and so there is more friction taking place between the boy and the grass.
How does friction help us move from place to place?
Friction does not help us.
Friction makes us slip and fall.
Friction keeps us from slipping and sliding.
What is air resistance?
It is the force that pulls objects towards the center of Earth.
It is the force that occurs when two objects rub against each other.
It is the force that acts on moving objects in the air.
Which force is taking place in this picture that slows down the skydiver?
Gravity
Air resistance
Magnetism
Which piece of paper will take longer to reach the ground if both are dropped from the same height at the same time?
The crumpled piece of paper, because it has a small surface and so there is more air resistance acting on it.
The flat piece of paper, because it has a large surface and so there is more air resistance acting on it.
What is the force that causes everything to be pulled down towards the center of the Earth?
Friction
Gravity
Air resistance
What is a force measured in?
Newton
Grams
Liters
Which force is shown in the picture?

Friction
Magnetism
What kind of forces are taking place in this picture?
Balanced forces
Unbalanced forces
Magnetism
In this picture, who will win the tug of war?
The children on the right, because they have more force.
The children on the left, because they have more force.
Nobody will win, because both sides have equal forces and so the rope will not move.

A man pushed a bicycle and a motorbike with the same amount of force. Which object will move slower?
The bicycle, because it has less mass and so it needs more force to move faster.
The motorbike, because it has more mass and so it needs more force to move faster.
Both will move at the same speed.

Gravity and magnetism
Gravity and air resistance
Gravity only
