Review: Unit 1 Newton's 2nd Law of Motion F=ma, m=F/a, a=F/m

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd Law of Motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. It can be expressed with the formula F=ma.

Front

What does the formula F=ma represent?

Back

The formula F=ma represents the relationship between force (F), mass (m), and acceleration (a). It indicates that force equals mass times acceleration.

How do you calculate mass using Newton's 2nd Law?

Back

Mass can be calculated using the formula m=F/a, where F is the force applied and a is the acceleration.

How do you calculate acceleration using Newton's 2nd Law?

Back

Acceleration can be calculated using the formula a=F/m, where F is the force applied and m is the mass of the object.
