A 4 kg object is dropped from a height. What is the force acting on it just before it hits the ground?

A 4 kg object is dropped from a height. What is the force acting on it just before it hits the ground?

Step 1: Identify the mass of the object. In this case, the mass is 4 kg.
Step 2: Understand that the force acting on the object just before it hits the ground is its weight.
Step 3: Use the formula for weight, which is F = mg, where F is the force (weight), m is the mass, and g is the acceleration due to gravity.
Step 4: Substitute the values into the formula. Here, m = 4 kg and g = 10 m/s².
Step 5: Calculate the force: F = 4 kg * 10 m/s² = 40 N.
Step 6: Conclude that the force acting on the object just before it hits the ground is 40 N.

Weight – The force acting on an object due to gravity, calculated as the product of mass and gravitational acceleration (F = mg).
Free Fall – An object in free fall experiences only the force of gravity acting on it, neglecting air resistance.
