Newton's 1st law
What is Newton's first law of motion?
An object in motion stays in motion and an object at rest remains at rest
What is Newton's 2nd law of motion
The acceleration of an object depends on its mass and the amount of force being applied to it
Every action has an equal and an opposite
According to Isaac Newton, when an object is in motion, what will cause it to stop?
An outside force
What is the equation of force?
mass x acceleration
For every action there is an equal and an opposite reaction, True or False?
True
Balanced forces are when two forces which act in opposite directions, are in equal size. If the forces on a box are balanced. One of the forces is 15N. What is the size of the other?
15N
As the mass of an object increases what else increases?
The net force needed to move the object.
When a moving bus suddenly stops, a person sitting will...?
Fall forward
According to Newton’s first law, a body in motion tends to remain in motion at a constant velocity. However, when you slide an object across a surface, the object eventually slows down and stops. Why?
The object experiences a frictional force exerted by the surface, and opposes it's motion
As the force of an object increases, what else increases.
the acceleration of the object.
Examples of Interaction Force Pair is a flying butterfly, true or false
True
The study of motion is called ______
Kinomatics
What is the net force acting on an object if it has a mass of 10 kg and an acceleration of 2 meters per second squared?
A swimmer pushes against the water, where will the swimmer be pushed? Forward or backward
Forward
