Force
Definition of Force
What is: A push or pull applied to an object
The maker of the Laws of Motion
Who is: Sir Issac Newton
Definition of Friction
What is: The force that opposes the sliding motion of two touching surfaces
Definition of Gravity
What is: any two masses that exert an attractive force on each other
Force is measured in
What is: Newtons
The 1st Law of Motion States (hint: the law of Inertia)
What is: An object in motion stays in motion, or an object at rest stays at rest until an unbalanced net force acts upon it
Definition of Static Friction
What is: two surfaces that are not moving past each other
Gravity depends on
What is: mass and distance between objects
Definition of a Net Force
What is: When two or more forces act on an object at the same time
Definition of Inertia
What is: Tendency of an object to resist any change in its motion
Definition of Sliding Friction
What is: two surfaces slide past one another
Definition of Weight
What is: a gravitational force exerted on an object. It's measured in units called Newtons
When one person on each side are pushing something
What is: the forces are balanced
The 2nd Law of Motion States
What is: A net force acting on an object causes the object to accelerate in the direction of the force.
Definition of Rolling Friction
What is: Friction between a rolling object and surface it rolls on.
Definition of Projectile Motion
What is: anything that is thrown or shot through air
When two people are pushing on one side and one is on the other
What is: the forces are unbalanced
The 3rd Law of Motion states
What is: For every action (or force), there is an equal and opposite reaction (or force).
Definition of Fluid Friction
What is: Friction when object moves through fluid, meaning either a liquid or gas
A Projectile follows
What is: a curved path and has horizontal motion or vertical motion
