Newtons Laws
Law of inertia
What is Newton's first law?
A push or pull exerted on an object
What is a force?
An object moves along a curved path under the action of gravity only
What is projectile motion?
a diagram showing all the forces acting on an object
What is free body diagram?
a series of images showing the positions of a moving object at equal time intervals
What is a motion diagram?
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
What is the Law of Inertia?
the speed and direction of a moving object
What is velocity?
The number or equations used to solve projectile problems
What is 4?
The amount of gravity on an object
What is F(gravity)?
Dots getting close together
What is slowing down?
From Newton's laws, used to find force, acceleration, or mass.
F=MA
The rate at which velocity changes
Angle for longest projectile motion
What is 45 degrees?
The force of a surface on an object
What is F(normal)?
Dots getting further apart
What is object speeding up?
The force of gravity acting on an object
What is weight?
the rate at which someone or something is able to move
What is speed?
9.81 m/s^2
What is the acceleration of gravity?
The force of an object being pulled
What is F(tension)?
Arrow point this way to represent velocity
What is the direction of movement?
The reason we don't accelerate downwards is that there is an "equal and opposite"
What is Newton's Third Law of Motion?
the resistance that one surface or object encounters when moving over another
What is friction?
The magnitude of velocity in the horizontal direction
what is 0?
The force of friction on an object
What is F(friction)?
Arrows point this was to represent negative velocity
What is away from motion?
