FIZIX1st Sem Review - Kinematics

Front

What does the symbol v₀ represent in kinematics?

Back

Initial Velocity (velocity when time is zero)

Front

How do you calculate the maximum altitude of a rocket fired upward?

Back

Use the formula: h = (v₀²) / (2g), where v₀ is the initial velocity and g is the acceleration due to gravity (9.8 m/s²).

Front

If an object accelerates from 0 to 40 m/s in 7 seconds, how do you find the distance traveled?

Back

Use the formula: distance = (initial velocity + final velocity) / 2 * time. Here, distance = (0 + 40) / 2 * 7 = 140 meters.

Front

What is the acceleration of a ball at its maximum height when V=0?

Back

The acceleration is -9.8 m/s² due to gravity.

Front

What is the acceleration of a ball on its way up?

Back

The acceleration is -9.8 m/s² due to gravity.

Front

Define acceleration in the context of kinematics.

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What is the formula for calculating average velocity?

Back

Average velocity = (initial velocity + final velocity) / 2.

Front

Explain the concept of free fall.

Back

Free fall is the motion of an object under the influence of gravitational force only, with no other forces acting on it.

Front

What is the significance of the acceleration due to gravity (g)?

Back

g is approximately 9.8 m/s² and represents the acceleration experienced by an object in free fall near the Earth's surface.

Front

How do you determine the time taken for an object to reach maximum height when thrown upwards?

Back

Use the formula: t = v₀ / g, where v₀ is the initial velocity.
