Buoyant, Gravitational, Friction, Magnetic, Balanced, and Unbalanced are all types of these.
What are forces?
100
Force
What is a push or pull?
100
A Zamboni machine at ice hokey or skating events scrapes the ice and sprays a layer of hot water over the surface during intermission. Why?
What is because it smooths the ice to reduce friction?
100
These forces act on a meteor as it falls toward Earth.
What are gravity and friction?
100
This is why simple machines make tasks easier.
What is they change the strength or direction of a force?
200
This causes a skateboard to stop rolling.
What is frictional force?
200
Gravitational Force
What is the force that depends on the masses of the objects and distances between them?
200
What object is responsible for pulling you and a ball to the ground?
What is Earth's gravitational force?
200
This is the reason it is easier to pull a box over pencils rather than without pencils.
What is because there is less friction between the pencils and the box?
200
This simple machine has a wheel with a groove for a rope.
What is a pulley?
300
This causes a ship to float.
What is buoyant force?
300
Magnetic force
What is a force exerted by a magnet?
300
This happens to forces when a parked car begins moving.
What is they become unbalanced?
300
These two forces cause a ball to roll down a hill.
What is gravity or someone pushing/kicking the ball?
300
This simple machine increases the distance and allows you to use less force (ex: ramp).
What is an inclined plane?
400
This pulls magnets together or pushes them apart.
What is a magnetic force?
400
Balanced force.
What are forces that act on an object, but cancel them out?
400
In what way is an object being pulled with a net force of 50N LIKE an object being pulled with -50N?
What is they are being pulled with the same amount of force?
400
This force is the reason you do NOT have to apply a push for your bike to move downhill, but you do to push it uphill.
What is gravity?
400
This is the balance part of a lever.
What is the fulcrum?
500
This type of force causes a "tie" when arm wrestling.
What is balanced force?
500
Unbalanced Force
What is the force that causes an object to move?
500
True or False: Only one force can act on an object at a time. You must give an example and name the different forces to get credit!
What is False? Answers will vary.
500
If one child pushes a chair to the left with a force of 100 N and another child pushes a chair to the right with 200 N, this is the net force.
What is 100 N to the right?
500
These are real-life examples of each type of simple machine.
