What is the formula for calculating work done when a force is applied over a distance?

Back

Work (W) = Force (F) × Distance (d) × cos(θ), where θ is the angle between the force and the direction of motion.

What is the unit of work in the International System of Units (SI)?

Back

The unit of work is the Joule (J). 1 Joule = 1 Newton × 1 meter.

How do you calculate the gravitational force acting on an object?

Back

Gravitational Force (F) = Mass (m) × Acceleration due to gravity (g), where g = 9.8 m/s².

What is the relationship between power, work, and time?

Back

Power (P) = Work (W) / Time (t). It measures how quickly work is done.

Front

What is the unit of power in the International System of Units (SI)?

Back

The unit of power is the Watt (W). 1 Watt = 1 Joule/second.

How do you calculate the momentum of an object?

Back

Momentum (p) = Mass (m) × Velocity (v). It is a vector quantity.

Front

What is the principle of conservation of momentum?

Back

In a closed system, the total momentum before an event is equal to the total momentum after the event.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = Change in Velocity (Δv) / Time (t). It measures how quickly an object changes its velocity.

Front

What is Newton's second law of motion?

Back

Newton's second law states that Force (F) = Mass (m) × Acceleration (a). It describes the relationship between an object's mass, the net force acting on it, and its acceleration.

What is the difference between kinetic energy and potential energy?

Back

Kinetic Energy (KE) is the energy of motion, calculated as KE = 1/2 mv². Potential Energy (PE) is stored energy based on position, calculated as PE = mgh.
