NEWTONS LAWS

Question 1

What are Newton’s Laws of motion?

Answer 1

Newton’s Laws of motion are three physical laws that describe the relationship between the motion of an object and the forces acting on it.

Question 2

What does the first law state?

Answer 2

An object will not change its motion unless a force acts on it.

Question 3

What does the second law state?

Answer 3

The force on an object is equal to its mass times its acceleration.

Formula: F = m × a

Question 4

What does the third law state?

Answer 4

When two objects interact, they apply forces to each other of equal magnitude and opposite direction.

Question 5

How do you calculate force using Newton’s second law?

Answer 5

Force is calculated using the formula: F = mass × acceleration.

Example: If mass (m) = 2 Kg and acceleration (a) = 5 m/s², then F = 2 × 5 = 10 N.

Question 6

What is an example calculation using the second law?

Answer 6

If mass (m) = 50 Kg and acceleration (a) = 2 m/s², then F = 50 × 2 = 100 N.

Question 7

What is the method for calculating force?

Answer 7

1. Write the equation: F = m × a
2. Identify the variables: mass and acceleration
3. Enter values
4. Calculate the result with units.
