a 50 gram object is accelerating at a rate of 5 m/s2. calculate the force needed to produce this acceleration
F = m*a
To calculate the force needed to produce the acceleration of an object, you can use Newton's second law of motion, which states that force (F) equals mass (m) multiplied by acceleration (a).
In this case, the mass (m) of the object is given as 50 grams. However, it is generally recommended to convert the mass to kilograms (kg) before calculation to maintain consistency with the SI unit system.
To convert grams to kilograms, divide the mass by 1000:
50 grams ÷ 1000 = 0.05 kg
Now that we have the mass in kilograms, we can calculate the force using the formula:
F = m * a
F = 0.05 kg * 5 m/s^2
F = 0.25 kg·m/s^2
So, the force needed to produce this acceleration is 0.25 Newtons.
