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 with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is inertia?

Back

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

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

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will be harder to change its state of motion.

Front

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

Back

Force equals mass times acceleration (F=ma). This means that a larger force is needed to accelerate a heavier object.

Front

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

Back

A passenger in a car lurches forward when the car suddenly stops because their body wants to continue moving forward.

Front

What happens to a nail when a hammer strikes it?

Back

The nail exerts the same amount of force back onto the hammer as the hammer exerts on the nail.

Front

What is an example of Newton's 3rd Law in action?

Back

When a rocket expels gas downwards, it moves upwards due to the reaction force.

Front

What is uniform circular motion?

Back

Uniform circular motion is the motion of an object traveling at a constant speed in a circular path.
