Inertia Basics
What is inertia?
What is an object's resistance to a change in motion.
Why does your body move forward when a car suddenly stops?
What is Your body wants to keep moving forward because of inertia.
Which has more inertia: a pencil or a textbook?
What is a textbook
What is the name of the property that makes an object resist changes in motion?
What is inertia
What force eventually slows down a rolling ball?
Friction and air resistance
What does Newton's First Law state about objects at rest?
What is it stays at rest unless acted on by an unbalanced outside force.
Why does a shopping cart continue rolling after you stop pushing?
Inertia keeps it moving until outside forces slow it down.
Why is it harder to push a car than a bicycle?
What is a car has more mass and greater inertia.
In the tablecloth experiment, why does the object stay in place when the cloth is pulled quickly?
The object resists changing its state of rest; friction acts only briefly.
If two objects have different masses, which one requires more force to stop if both are moving at the same speed?
The object with more mass, assuming the same speed.
What happens to an object in motion if no unbalanced outside force acts on it?
What is it continues moving at a constant velocity in a straight line.
Why do seatbelts help protect you during a car accident?
What is They apply a force that slows your body with the car.
Why does a loaded truck take longer to speed up than an empty truck?
More mass means more inertia, requiring more force to accelerate.
What happens when you slowly pull the card from underneath an object?
Friction transfers motion to the object, causing it to move with the card.
Why is it harder to stop sprinting than jogging?
Sprinting involves greater momentum, so more force is needed to stop.
What is the relationship between mass and inertia?
What is more mass means more inertia
Why do athletes lean backward when stopping suddenly?
What is their bodies continue moving forward because of inertia.
Why do elephants have more difficulty changing their motion than rabbits?
Elephants have greater mass and inertia.
In the tower challenge, why is a quick pull more successful than a slow pull?
A quick pull reduces the time friction has to move the object.
Give an example of Newton's First Law in your everyday life and explain how it demonstrates inertia.
What is the ability to resist motion
What is Newton's first name?
What is Isaac
What happened in a slow pull?
What is cup and index card stay together
What is force?
What is a push or pull on an object
What is mass?
What is gravity?
A force that draws objects to the center of the earth...keeps things on the ground.
