Force
These two forces act on objects without touching them.
What are gravity and magnetism?
Newton's First Law
an object at rest will stay at rest and an object in motion will stay in motion until a force acts upon it.
These are three ways to describe motion.
These are three ways to describe motion.What are position, direction, and speed?
The higher the velocity and mass, the more momentum an object has. One way to think of momentum is that momentum measures how hard it will be to stop the object once it is in motion. Momentum can be transferred when two objects collide.
What is Momentum?
You can apply this to reduce friction between two surfaces.
What is a lubricant?
The needle of a compass moves because of Earth's ______.
What is magnetism?
Force equals mass times acceleration.
What is Newton's Second Law?
Three words to describe position are ____________, _____________, ________________.
What are behind, beside, and below? or: ahead of, in front of, above?
The changes in an object’s motion. This can be speeding up, slowing down or changing direction. An object’s acceleration depends on the object’s mass and the force applied.
What is acceleration?
A ball has two forces acting on it. One force is pushing it to the left and a larger force is pushing it to the right. This is the direction the ball will move.
What is right?
This force opposes motion between two surfaces that are touching.
What is friction?
When you jump or your legs apply a force to the ground _________ this is an example of which of Newton's laws?
Newton's 3rd law of Motion.
These are three words that describe direction.
What are north, south, and east? also: left or right?
Energy of motion.
What is Kinetic Energy?
An object is in a state of ____________ when all the forces acting on it balance each other.
What is equilibrium?
_____________ forces have a net force of zero.
What are balanced?
When forces act on an object without changing its motion.
What is balanced force?
These types of forces cause motion.
What are unbalanced forces?
The way we learn and study the world around us through a process of steps. (Six Giant Hippos Eat Red & Orange Candy)
What is scientific method?
A ball is rolling and eventually comes to a stop. __________ is the force most likely responsible for this.
What is friction?
These are three variables that affect friction.
What are texture, mass, and lubrication?
The push of an object on a second object then the push of the second object back on the first object
What are action and reaction forces?
You put two blocks on a table. Block A moves toward Block B without anything touching it. This feature of Block B can explain why this is happening.
What is magnetic?
Example....F=MA F = force M = mass A = acceleration
Newton’s 2nd Law of Motion.
If there are two objects with the same mass and one is acted on by a greater force than the other one, the one acted on by a greater force will have the greatest change in ________________.
What is speed?
