Newton's Laws Review

Front

The acceleration due to gravity is _____?

Back

9.8 m/s^2

Front

To increase acceleration, you need to increase _____?

Back

force

Front

What law of motion states that an object at rest stays at rest unless acted upon by a net force?

Back

Newton's 1st law

Front

Fn stands for _____?

Back

Force normal

Front

What is the formula to calculate mass using force and acceleration?

Back

m = F/a

Front

What is the net force acting on an object if it has a mass of 3 kg and is accelerating at 5 m/s²?

Back

15 N (F = ma)

Front

What does Newton's 2nd law state?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

If a net force of 20 N is applied to a 4 kg object, what is its acceleration?

Back

5 m/s² (a = F/m)

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass (W = mg).
