'24: Norman: 7th Grade: Newton's 1st Law of Motion

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It means that 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 First Law of Motion state?

Back

Newton's First Law of Motion states that an object will remain at rest or in uniform motion in a straight line unless acted upon by a net external force.

Front

What kind of objects have inertia?

Back

All objects with mass have inertia.

Front

What is the Law of Inertia?

Back

The Law of Inertia is another name for Newton's First Law of Motion, which describes the behavior of objects in motion or at rest.

Front

What happens to a car moving at a constant speed in a straight line?

Back

The forces acting on the car are balanced, meaning there is no net force causing a change in motion.

Front

What is a force?

Back

A force is a push or pull exerted on an object that can cause it to change its motion.

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal and opposite, resulting in a change in the motion of an object.

Front

What is an example of inertia in everyday life?

Back

When a car suddenly stops, passengers lurch forward due to inertia, as their bodies want to continue moving in the same direction.

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.
