Newtons 3 Laws Review

Front

What is inertia?

Back

Inertia is the resistance of an object to change its motion. It is directly related to the mass of the object.

Front

How do you calculate net force?

Back

Net force can be calculated using the formula: Net Force = Mass x Acceleration (F = ma).

Front

What is the weight of an object on Earth?

Back

Weight is the force exerted by gravity on an object, calculated as Weight = Mass x Gravitational Acceleration (W = mg). On Earth, g is approximately 9.8 m/s².

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by a net external force.

Front

What is Newton's Second Law of Motion?

Back

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

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

If a 7 kg bowling ball accelerates to 10 m/s in 2 seconds, what is the net force acting on it?

Back

The net force is 35 N.

Front

What direction does the net force act on an object moving rightward?

Back

The net force acts in the same direction as the motion, which is rightward.

Front

How much does a 1.5 kg ferret weigh on Earth?

Back

The ferret weighs approximately 15 N.

Front

Which object requires the most force to maintain circular motion?

Back

The Earth going around the Sun requires the most force to maintain its circular path.
