Question

it an object is meaning in a straight line with the acceleration of 7m/s and the force it generate it has a mass of 600 gm?​

Answer 1

Given :

Mass of body = 600g = 0.6kg

Acceleration = 7m/s²

To Find :

Magnitude of force.

Solution :

❖ As per newton's second law of motion, force is measured as the product of mass and acceleration.

Mathematically, F = m a

» F denotes force

» m denotes mass

» a denotes acceleration

By substituting the given values;

➠ F = m × a

➠ F = 0.6 × 7

➠ F = 4.2 N

Knowledge BoosteR :

• Force is a polar vector quantity as it has a point of application$.$
• Force can be classified as positive and negative. A positive force represents repulsion and a negative force represents attraction
