Kinematics
Net change in position.
What is displacement?
Has a value of -9.81 m/s2
What is the gravitational acceleration on Earth?
Collision in which two objects stick together.
What is a perfectly inelastic collision?
Line about which circular motion takes place.
What is the axis of rotation?
Represents mass per unit volume in a fluid.
What is mass density?
Displacement divided by time interval of the displacement.
What is average velocity?
Causes changes in motion.
What is a force?
Collision in which kinetic energy and momentum is conserved.
What is an elastic collision?
Net force towards the center of a circular motion path.
What is the centripetal force?
Force that keeps an object afloat.
What is the buoyant force?
Motion of an object under the action of gravity only.
What is freefall?
States that an object in motion stays in motion without the action of an outside force.
What is Newton's First Law?
Used to determine final velocity in a completely inelastic collision.
What is conservation of momentum?
Physicist who formulated the Law of Universal Gravitation.
Who is Isaac Newton?
Force exerted by a fluid per unit area.
What is pressure?
What is projectile motion?
Calculated using (1/2)mv2
What is kinetic energy?
Product of the force and the time interval over which it is applied.
What is impulse?
Set of three laws that describe planetary motion.
What are Kepler's Laws?
Internal friction in a fluid.
What is viscosity?
Shape of the trajectory described by a projectile.
What is a parabola?
Sum of kinetic and potential energy.
What is mechanical energy?
In an inelastic collision, some kinetic energy is converted into this.
What is internal elastic potential energy?
Time taken by a planet to complete one full cycle around the Sun.
What is period?
States that pressure in a fluid decreases as velocity increases.
What is Bernouilli's principle?
