Physics Semester-1 Review

Front

What is Potential Energy?

Back

Potential Energy is the energy possessed by an object due to its position or configuration. It is calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

Calculate the Potential Energy of a 10 kg object lifted to a height of 5 meters. (Use g = 9.8 m/s²)

Back

490 J

Front

What is the definition of Distance in physics?

Back

Distance is a scalar quantity that represents the total path length traveled by an object, regardless of direction.

Front

What is the total distance traveled if a car drives 10 m east, 15 m west, and then 5 m east?

Back

30 m

Front

What is Acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time. It is a vector quantity and is measured in meters per second squared (m/s²).

Front

What is the unit for Acceleration?

Back

Meters per second squared (m/s²).

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object due to its motion, calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

Calculate the Kinetic Energy of a 3 kg object moving at a velocity of 4 m/s.

Back

48 J

Front

What is the formula for calculating Kinetic Energy?

Back

KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the definition of Velocity?

Back

Velocity is a vector quantity that refers to the rate at which an object changes its position, including direction.
