Flashcard on Newtons Law Of Motion

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is Newton's 2nd 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 3rd Law of Motion?

Back

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

Front

Who formulated the laws of motion?

Back

Isaac Newton.

Front

What is the formula for calculating weight?

Back

Weight (W) = mass (m) × gravity (g).

Front

What is the value of gravity on Earth?

Back

9.8 m/s².

Front

If an object has a mass of 10 kg, what is its weight on Earth?

Back

Weight = 10 kg × 9.8 m/s² = 98 N.

Front

What does inertia mean in the context of Newton's laws?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is an example of Newton's 1st Law?

Back

A soccer ball remains still until a player kicks it.

Front

What is an example of Newton's 2nd Law?

Back

A heavier object requires more force to accelerate than a lighter object.
