What is a force?
A push or a pull
100
This is a measure of how fast something moves.
What is speed?
100
If a ball changes direction, are the forces acting on it balanced or unbalanced.
Unbalanced forces cause a CHANGE in speed OR direction.
100
These two forces get weaker as their distance from another object increases.
What is gravity and magnetism.
100
What is the unit for force?
Newtons (N)
200
What is a balanced force?
What is when 2 forces act on something but there is no change in motion or position.
200
A force that slows down objects when they rub against each other
What is friction?
200
The force that pulls objects towards the center of the Earth
What is gravity?
200
What is one way to make a cart go faster?
What is push or pull it harder? (or reduce the force of friction)...other possible answers.
200
Who discovered the laws of motion?
Who is Isaac Newton?
300
A change in position
What is motion?
300
Which has more friction: walking on a floor in bare feet or socks?
What is walking on a floor in bare feet?
300
What is the net force?
What is 0 Newtons?
300
True or false: There is no gravity in space.
What is false?
300
True or false - an object has to be at rest in order for the forces acting on it to be balanced.
What is false.
An object will move with a constant speed and direction if the forces acting on it are balanced.
400
What is an unbalanced force?
What is when 2 forces act on an object and there is a change in position or motion.
400
50 N right and 60 N left will result in.
10 N left
400
What type of force must this boy use to make a basket? What other force will act on the ball?
What is he must push the ball. Gravity will also act on the ball making it fall down (either in the hoop or not).
400
A marble falls to Earth faster than a feather due to this force.
What is air resistance / air friction / drag.
400
This is the force of attraction among all objects with mass
What is gravity?
500
Something moving has this type of energy.
What is mechanical energy.
500
As the speed of an object increases, what happens to it mechanical energy.
The mechanical energy increases.
500
How will this object move?
What is it will move to the right?
500
If the 5th grade is playing tug of war in gym and no one is moving, is this a balanced or unbalanced force?
What is balanced force?
500
If an object speeds up, are the forces acting on it balanced or unbalanced.
Unbalanced Forces cause a CHANGE in speed OR direction.
