Newton's Laws of Motion Flashcard

Front

What does Newton's First Law of Motion state?

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

Define inertia in the context of Newton's Laws of Motion.

Back

Inertia is the property of an object to resist changes in its state of motion or rest.

Front

What is the formula for calculating force according to Newton's Second Law of Motion?

Back

F = ma, where F is force, m is mass, and a is acceleration.

Front

What is the significance of Newton's Third Law of Motion?

Back

It states that for every action, there is an equal and opposite reaction.

Front

How does mass affect acceleration when a constant force is applied?

Back

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

Front

What is the net force acting on an object that is in equilibrium?

Back

The net force is zero.

Front

Explain the concept of action and reaction forces with an example.

Back

Action and reaction forces are equal in magnitude and opposite in direction; for example, when you push against a wall, the wall pushes back with equal force.

Front

What is the relationship between force, mass, and acceleration?

Back

The relationship is described by Newton's Second Law: Force is equal to mass times acceleration (F = ma).

Front

What happens to the motion of an object if no net force acts on it?

Back

The object will maintain its current state of motion, either at rest or moving at a constant velocity.

Front

How can you determine if an object is experiencing balanced forces?

Back

If the net force acting on the object is zero, the forces are balanced.
