Correct
Accuracy
Whenever one object exerts a force on another, the second object exerts an equal and opposite force on the 1st.
Newton’s 3rd law
Repeat
Precision
The resistance of a body to change its state of motion
Inertia
The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass
Newton’s 2nd law
The amount so matter an object has;a measure of an objects’ inertia ; measured in grams or kg
Mass
The total momentum of interacting objects equals the total momentum afterwards
Conservation of momentum
Occur when two or more objects hit each other.
Collision
Energy that comes from motion
Kinetic
A unit for work or energy
Joule
A force created by gravity acting on mass
Weight
A quantity that has both magnitude and direction
Vector
Occur when the force son an object one balance and net force =o;in harmonic motion, undistrubed
Equilibrium
A single vector that is the sum of a group of vectors.
Resultant vector
The metric unit of force
Newton
An object in orbit around another object with gravity provided the centripetal force
Satellite
A regular repeating path that an object in space follows around another object caused by the influence of gravity
Orbit
To move around, or orbit, an external axis
Revolve
The curved path a projectile follows
Trajectory
The effect of inertia on an object to moving in a curve;is not a true force;”apparent”
Centrifugal
The point at which an object naturally spins
Center of mass
To spin around an axis of rotation that passes through an object
Rotate
The distance a projectile travels horizontally
Range
A force that causes an object to move in a circle
Centripetal
