What is the difference between simple harmonic motion and periodic motion? Answer: Simple harmonic motion refers to a type of periodic motion in which the restoring force is directly proportional to the displacement from the equilibrium position, while periodic motion refers to any motion that repeats itself after a certain time interval.
What is the difference between velocity and acceleration? Answer: Velocity is a vector quantity that represents the rate of change of displacement, while acceleration is a vector quantity that represents the rate of change of velocity.
What is the difference between speed and velocity? Answer: Speed is a scalar quantity that represents the rate of change of distance, while velocity is a vector quantity that represents the rate of change of displacement.

What is the difference between instantaneous velocity and average velocity? Answer: Instantaneous velocity is the velocity of an object at a specific instant in time, while average velocity is the total displacement divided by the total time taken.
What is the difference between uniform motion and non-uniform motion? Answer: Uniform motion is when an object covers equal distances in equal intervals of time, while non-uniform motion is when an object covers unequal distances in equal intervals of time or equal distances in unequal intervals of time.
What is the difference between linear motion and angular motion? Answer: Linear motion refers to motion in a straight line, while angular motion refers to motion around an axis or a point.
What is the difference between translational motion and rotational motion? Answer: Translational motion refers to motion in which all parts of an object move in the same direction and at the same speed, while rotational motion refers to motion around an axis or a point.

What is the difference between positive acceleration and negative acceleration? Answer: Positive acceleration occurs when an object's velocity increases over time, while negative acceleration (also known as deceleration or retardation) occurs when an object's velocity decreases over time.
What is the difference between linear momentum and angular momentum? Answer: Linear momentum refers to the momentum of an object moving in a straight line, while angular momentum refers to the momentum of an object rotating around an axis or a point.
What is the difference between translational equilibrium and rotational equilibrium? Answer: Translational equilibrium occurs when the net force acting on an object is zero, while rotational equilibrium occurs when the net torque acting on an object is zero.
What is the difference between elastic and inelastic collisions? Answer: In an elastic collision, both momentum and kinetic energy are conserved, while in an inelastic collision, momentum is conserved, but kinetic energy is not conserved.
What is the difference between static equilibrium and dynamic equilibrium? Answer: Static equilibrium occurs when an object is at rest and the net force and net torque acting on it are both zero, while dynamic equilibrium occurs when an object is in motion with a constant velocity and the net force and net torque acting on it are both zero.
What is the difference between force and pressure? Answer: Force is a push or pull that can cause an object to accelerate or deform, while pressure is the force exerted per unit area.
What is the difference between mass and weight? Answer: Mass is a measure of the amount of matter in an object and remains constant regardless of the location, while weight is the gravitational force acting on an object and varies with the strength of the gravitational field.
What is the difference between static friction and kinetic friction? Answer: Static friction is the force that opposes the initiation of motion between two surfaces in contact, while kinetic friction is the force that opposes the relative motion between two surfaces in contact when they are already in motion.
What is the difference between work and power? Answer: Work is the transfer of energy that occurs when a force is applied to an object and it moves in the direction of the force, while power is the rate at which work is done or energy is transferred.
What is the difference between potential energy and kinetic energy? Answer: Potential energy is the energy an object possesses due to its position or condition, while kinetic energy is the energy an object possesses due to its motion.
What is the difference between speed and velocity? Answer: Speed is a scalar quantity that represents the rate of change of distance, while velocity is a vector quantity that represents the rate of change of displacement.
