ii. newtons second law of motion

1. newton’s second law of motion is also known as the law of
2. newton’s second law says that when an force is applied to a , it causes it to
3. the greater the force that is applied, the the acceleration.
4. the lesser the force that is applied, the the acceleration.
5. if the same force is applied to an object with a large mass, it will have a acceleration.
6. if the same force is applied to an object with a small mass, it will have a acceleration.
7. the equation that is used to solve second law problems is f = ma.

a. what do each of the variables mean?
f = m = a =
b. what unit of measurement must be used with each variable?
f = m = a =

Explanation:

1. Newton's second law is also known as the law of acceleration as it relates force, mass and acceleration.
2. It states that when an unbalanced force is applied to a mass, it causes it to accelerate.
3. According to the formula F = ma, the greater the force, the greater the acceleration.
4. The lesser the force, the lesser the acceleration.
5. With the same force, a large - mass object will have a small acceleration as a = F/m.
6. With the same force, a small - mass object will have a large acceleration as a = F/m.

12a. In F = ma, F is force, m is mass and a is acceleration.
12b. The unit of force is Newton (N), the unit of mass is kilogram (kg) and the unit of acceleration is meter per second squared (m/s²).

Answer:

1. Acceleration
2. Unbalanced; mass; accelerate
3. Greater
4. Lesser
5. Small
6. Large

12a. F = Force; m = Mass; a = Acceleration
12b. F = Newton (N); m = Kilogram (kg); a = Meter per second squared (m/s²)
