Newton's First Law of Motion
Which object has the least inertia? Ant, Firetruck, Bowling Ball
Ant because it has the least amount of mass.
What is the relationship between force and acceleration?
More force leads to more acceleration (less force is less acceleration)
What is the unbalanced force that will eventually stop any moving object?
Friction
What is the relationship between mass and force?
More mass needs more force to move it (less mass needs less force)
Describe inertia.
What is the relationship between mass and acceleration?
More mass leads to less acceleration (less mass, more acceleration)
A moving skateboarder hits a curb and the skateboard comes to an abrupt stop. What happens to the person on the skateboard and WHY?
They will fly forward, continuing their motion, because an object in motion will stay in motion unless acted on by an unbalanced force.
The same engine is put into three different vehicles. Which vehicle will have the most acceleration and why? Race car, semi truck, train
Racecar because it has the least amount of mass.
DAILY DOUBLE: What is Newton’s First Law of Motion?
An object in motion will stay in motion, and an object at rest will stay at rest, unless acted on by an unbalanced force.
What are the THREE examples of acceleration?
Speeding up, slowing down, and changing direction
