SCIENCE Flashcards
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of an object.
LAW OF ACCELERATION
F = ma. TRUE OR FALSE?
TRUE
Is the change in position of an object over time.
MOTION
MOTION can be either one-dimentional or two-dimentional. TRUE or FALSE?
TRUE
Vector distance, change in position
DISPLACEMENT
Rate of change in displacement
VELOCITY
Rate of change in velocity
ACCELERATION
Interval of which change occurs
TIME
An object that undergoes projectile motion
PROJECTILE
The path that the projectile follows.
TRAJECTORY
TYPES OR PARABOLIC PROJECTILE
NON-ANGLED AND ANGLED
Is horizontally thrown.
NON-ANGLED PROJECTILE
The horizontal and vertical component is DEPENDENT of each other. TRUE or FALSE?
TRUE
Horizontal Velocity is always CONSTANT, wherein acceleration is equal to 0. TRUE or FALSE?
TRUE
Vertical Velocity changes over time due to the influence of MASS. TRUE or FALSE?
FALSE. It is due to the influence of GRAVITY.
The value of acceleration in free fall is always constant so the value of gravity is?
-9.8 m/s^2
Projected at an angle to the horizontal
ANGLED PROJECTILE
A numerical value in degrees (°) expressing the orientation of the projectile to be projected/thrown
ANGLE
Vertical velocity; the projectile to travel at a vertical distance
Vy
Horizontal velocity; the projectile to travel at a horizontal distance
Vx
The max. vertical distance from the Earth a projectile can reach
MAXIMUM HEIGHT
The horizontal distance covered by a projectile.
RANGE
It is a moving object’s tendency to resist any change in its state of motion
It depends on mass and velocity
It is a vector quantity with the SI unit of kg · m/s
MOMENTUM
LESS HEAVIER OBJECTS have GREATER momentum. TRUE or FALSE?
FALSE. HEAVIER OBJECTS.
