General Physics I (Mechanics, Thermal Physics and Waves)

These flashcards cover fundamental concepts of mechanics, including motion types, kinematics, distance, displacement, speed, velocity, and projectile motion.

Kinematics is the study of __ without regard to the forces or energies involved.

Motion.

The five types of motion in physics are translational, random, oscillatory, __, and circular motion.

Rotational.

The metric unit for measuring distance is __.

meters (m).

Displacement is a __ quantity, while distance is a scalar quantity.

Vector.

Acceleration is defined as the rate of change of __ with respect to time.

Velocity.

A body moving with uniform speed travels equal distances in equal intervals of __.

Time.

When a falling object experiences no air resistance, it is said to be in __ motion.

Free fall.

The acceleration due to gravity is approximately __ m/s² near the surface of the Earth.

9.8.

The velocity of a projectile in the x-direction is __, while in the y-direction, it changes due to gravity.

Constant.

The two components of projectile motion are __ and vertical motion.

Horizontal.

The formula for calculating maximum height (H) in projectile motion when projected at angle A is __.

H = (u² sin² A) / (2g).

Distance is always __, whereas displacement can be positive, negative, or zero.

Positive.

In two-dimensional projectile motion, the path taken is called a __.

Trajectory.

Instantaneous speed is the speed of an object at any instant, as opposed to __ speed which is averaged over a time interval.

Average.

The branch of mechanics that describes motion without reference to forces is called __.

Kinematics.

The difference between the final position and the initial position of a body is called __.

Displacement.
