Newton's Laws

Front

What is the sum of all forces acting on an object?

Back

Net force is the sum of all forces acting on an object, capable of accelerating a mass.

Front

What does Newton's 1st law state?

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 does Newton's 2nd law describe?

Back

Newton's 2nd law states that 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?

Back

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

Front

What is inertia?

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 at rest until kicked by a player.

Front

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

Back

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

Front

What is an example of Newton's 3rd law?

Back

When you jump off a small boat, the boat moves backward as you move forward.

Front

What is the relationship between mass and acceleration according to Newton's 2nd law?

Back

As mass increases, acceleration decreases if the net force remains constant.

Front

What is the definition of net force?

Back

Net force is the vector sum of all individual forces acting on an object.
