Kinematics 1B Review

Front

What is Kinematics?

Back

Kinematics is the branch of physics that describes the motion of objects without considering the forces that cause the motion.

Front

Define Scalar Quantity.

Back

A scalar quantity is a physical quantity that has magnitude only and no direction, such as mass, temperature, or speed.

Front

Define Vector Quantity.

Back

A vector quantity is a physical quantity that has both magnitude and direction, such as velocity, force, or displacement.

What is the formula for calculating the time of free fall from a height?

Front

What is the Head to Tail Method in vector addition?

Back

The Head to Tail Method involves placing the tail of one vector at the head of another vector to find the resultant vector.

Front

What is the difference between horizontal and vertical motion?

Back

Horizontal motion is motion along the x-axis, while vertical motion is motion along the y-axis. In projectile motion, horizontal and vertical motions are independent of each other.

Front

How does air resistance affect the motion of a projectile?

Back

Air resistance opposes the motion of a projectile, reducing its speed and altering its trajectory compared to motion in a vacuum.

Front

What is the significance of the resultant vector?

Back

The resultant vector is the single vector that has the same effect as two or more vectors acting together. It is found by vector addition.

Front

Explain the concept of projectile motion.

Back

Projectile motion is the motion of an object that is thrown or projected into the air, subject to the acceleration of gravity, following a curved path.
