Class 9 Physics Test

A 2 kg block is pulled with a force of 6 N. What is the acceleration of the block?

An object thrown upwards with an initial velocity of 20 m/s will eventually come to rest at its maximum height. (True or False)

What is the work done by a force of 5 N in moving an object through a distance of 2 meters?

The acceleration of an object under gravity is _______________ m/s².

Match the following physical quantities with their corresponding units:

Class 9 Physics Test Topics

Laws of Motion

Covers Newton's 2nd Law and Law of Conservation of Momentum
Numerical questions on: • Newton's 2nd Law (F = ma) • Law of Conservation of Momentum (total momentum before collision = total momentum after collision)

Kinematics

Covers Equations of Motion, Free Fall, Motion under Gravity, Speed, Velocity, and Acceleration
Questions from: • Equations of Motion (v = u + at, s = ut + 0.5at^2, v^2 = u^2 + 2as) • Free Fall ( acceleration due to gravity, g = 9.8 m/s^2) • Motion under Gravity (projectile motion, trajectory, range) • Speed, Velocity, and Acceleration (scalar, vector, and instantaneous values)

Work, Energy, and Power

Covers Work-Energy Theorem, Work, Energy, and Power
Questions from: • Work-Energy Theorem (W = ΔE, energy transferred = work done) • Work (scalar, measured in joules, J) • Energy (kinetic, potential, and total energy) • Power (rate of doing work, measured in watts, W)
