What is the measure of the amount of matter in an object?
The measure of the amount of matter in an object is called its mass.
How much force in Newtons is required to accelerate a 5 kg bowling ball at 2 m/s2
The force required to accelerate a 5 kg bowling ball at 2 m/s^2 can be calculated using Newton's second law of motion, which states that force (F) equals mass (m) multiplied by acceleration (a).
F = m * a
F = 5 kg * 2 m/s^2
F = 10 N
Therefore, 10 Newtons of force is required to accelerate a 5 kg bowling ball at 2 m/s^2.
