2D Kinematics
Change in position
What is displacement?
The path of a Projectile
What is a trajectory?
the first man who initially investigated about the concept of inertia
Galileo Galilei
a force that causes a change in motion by opposing it.
What is Friction?
pushes and pulls
What are forces?
the velocity of an object at that instant
What is instantaneous velocity vector?
Zero Vertical velocity
What is the projectile's vertical velocity at the peak of its flight?
The philosopher behind motion being either natural or unnatural.
Who is Aristotle?
anything inside an imaginary boundary chosen by the physicist.
What is a system?
enables an object to change its state of motion
What are unbalanced forces?
a coordinate system within which motion is observed or measured.
what is a frame of reference?
any flying object that is given an initial velocity, and is then influenced only by external forces, such as gravity
What are projectiles?
hypothesis based on conjecture rather than observation, usually in an attempt to explain a natural phenomenon.
What is an ad hoc hypothesis?
ΣF = ma
What is the 2nd law of motion?
a force that pulls things apart
What is a tensile force?
acceleration at a particular moment
What is instantaneous acceleration
The unpowered portion of a projectile's path
What is ballistic trajectory?
The scientist who studied about gravitation and published a book called Principia.
Who is Isaac Newton?
The force of planetary gravitational attraction on an object
What is weight?
action-at-a-distance forces
What are noncontact forces?
a motion that has been initially propelled horizontally and allowed to fall in a ballistic trajectory
An object will continue in its original state of motion unless some outside agent acts on it.
What is Galileo's Principle of Inertia?
A resultant force of 1 N, when applied to a mass of 1 kg, produces an acceleration of 1 m/s².
What is the definition of the derived unit Newton?
a fundamental force that causes nuclear decay
weak nuclear interaction force
