Physics Sem 1 Review part 2

Front

What is the formula for calculating work?

Back

Work (W) = Force (F) × Distance (d)

Front

How do you calculate force using mass and acceleration?

Back

Force (F) = Mass (m) × Acceleration (a)

Front

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

Back

Power (P) = Work (W) / Time (t)

Front

How do you calculate kinetic energy?

Back

Kinetic Energy (KE) = 1/2 × Mass (m) × Velocity² (v²)

Front

What is the formula for gravitational potential energy?

Back

Potential Energy (PE) = Mass (m) × Gravity (g) × Height (h)

Front

What is the unit of work?

Back

The unit of work is the Joule (J).

Front

What is the unit of power?

Back

The unit of power is the Watt (W).

Front

How do you find the speed of an object using kinetic energy?

Back

Speed (v) = √(2 × Kinetic Energy (KE) / Mass (m))

Front

What is the formula for calculating velocity just before an object hits the ground?

Back

Velocity (v) = √(2 × g × h)

Front

What does the term 'net force' mean?

Back

Net force is the total force acting on an object after all the forces are combined.
