Force
The combination of all the forces acting on an object
What is net force
A measure of how quickly the velocity of something is changing. It can be positive if the object is speeding up or negative if the object is slowing down.
What is acceleration
V=d/t
What is the velocity formula
An object at rest will remain at rest and an object in motion will continue moving at a constant velocity unless acted upon by a net force
What is newton’s First law of inertia
A unit of measure that equal the force required to accelerate one kilogram of mass at 1 meter per second
What is newton
Forces acting on an object that combine and form a net force of zero
What is balanced forces
The distance traveled in a particular direction. Is a vector unlike distance.
What is displacement
Average speed=distance travelled/time of travel
What is the average speed formula
The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass
What is newton’s Second law of motion
The force that one surface exerts on another when the two rub against each other
Friction
A net force that doesn’t equal zero, which changes an objects motion
What is unbalanced forces
How far something has travelled. Is a scalar and has no direction.
What is distance
S=d/t
What is the speed formula
For every action force there is an equal and opposite reaction force
What is Newton’s third law of motion
When air resistance balances out weight of a falling object, it will fall at this constant velocity
Terminal velocity
The tendency of an object to resist any change in motion
What is inertia
A measure of distance an object travels in a given time. Usually measured in meters per second(m/s). It is a scalar quantity.
What is speed
A=Vf-Vi/t
What is the acceleration formula
The amount of matter in an object
What is mass
This states that the total momentum in a collision is maintained
What is the law of conservation of momentum
The earth’s natural force
What is gravity
The speed of an object in a particular direction. Usually measured in meter per second(m/s). It is a vector, speed is not.
What is velocity
F=ma
What is the force formula
Amount of motion of a moving object (p=mv)
What is momentum
9.8 m/s/s
The acceleration rate due to gravity on earth
