a push or pull that is needed to start an object moving
What is a force?
100
the force that acts between objects that have mass, causing them to attract each other
What is gravity?
100
An object at rest will not move until a net force acts on it. An object that is moving will keep moving at the same speed and in the same direction until a net force acts on it.
What is Newton’s First Law of Motion?
100
refers the location of an object
What is position?
100
Using WD40 would effect this type of force.
What is friction?
200
the combination of forces acting on an object
What are net forces?
200
a force that is present between objects or surfaces that are touching, opposing, or acting against their motion
What is friction?
200
For every action force acting on an object, the object will apply an equal and opposite reaction force.
What is Newton’s Third Law of Motion?
200
refers to the change of position of an object
What is motion?
200
The Moon orbiting the Earth is an example of this type of force.
What is gravity?
300
the forces produced by a magnet
What are magnetic forces?
300
any change in an object’s velocity
What is acceleration?
300
this is dependant on how much gravitational force is present
What is weight?
300
how far it is from one point to another
What is distance?
300
When using a compass, this type of force is being used.
What is magnetism?
400
these types of forces result in a net force that is not zero
What are unbalanced forces?
400
distance/time
What is the formula for Speed?
400
An object’s acceleration depends on the amount of force acting on the object and the object’s mass. An object acted on by a net force will accelerate in the direction of the net force
What is Newton’s Second Law of Motion?
400
the measure of an object’s change in position over time
What is speed?
400
A rolling ball that slowly comes to a stop in the center of a grassy field is an example of this type of force.
What is friction?
500
these types of forces result in a net force of zero
What are balanced forces?
500
(final velocity - initial velocity)/time
What is the formula for acceleration?
500
a property that describes how objects tend to resist changes in motion
What is inertia?
500
the measure of an object’s speed in a certain direction
What is velocity?
500
The force of gravity is dependant on these two things.
What are the distance between two objects and the masses of the two objects?
