Question: If a 2 kg object is moving with a velocity of 3 m/s, what is its kinetic energy?

Options:

Correct Answer: 9 J

Solution:

Kinetic Energy = 0.5 * m * v² = 0.5 * 2 kg * (3 m/s)² = 9 J.

If a 2 kg object is moving with a velocity of 3 m/s, what is its kinetic energy?

If a 2 kg object is moving with a velocity of 3 m/s, what is its kinetic energy?

Step 1: Identify the mass (m) of the object. In this case, m = 2 kg.
Step 2: Identify the velocity (v) of the object. Here, v = 3 m/s.
Step 3: Use the formula for kinetic energy: Kinetic Energy = 0.5 * m * v².
Step 4: Substitute the values into the formula: Kinetic Energy = 0.5 * 2 kg * (3 m/s)².
Step 5: Calculate (3 m/s)², which is 9 m²/s².
Step 6: Multiply 0.5 * 2 kg = 1 kg.
Step 7: Now multiply 1 kg by 9 m²/s² to get 9 J.
Step 8: Conclude that the kinetic energy of the object is 9 Joules.

Kinetic Energy – Kinetic energy is the energy an object possesses due to its motion, calculated using the formula KE = 0.5 * m * v², where m is mass and v is velocity.
