Newton's Laws of Motion
An object at rest stays at rest and an object in motion stays in motion unless an unbalanced force acts on it.
What is Newton's 1st Law of Motion?
If a semi-truck and a prius collide, what kind of force do they exert on each other?
Equal and opposite
A layer of ice on cement reduces/increases friction.
Reduces
In the formula F=m*a, F stands for:
Force
The unit Newton (N) is used when talking about
Force
Acceleration of an object depends on the mass and the amount of force applied.
What is Newton's 2nd Law of Motion?
If a meteor collides with the moon, which one exerts a greater force during the collision?
Neither, they exert an equal and opposite force on each other!!!
Putting chains on your vehicle's tires during a snow storm reduces/increases friction.
Increases
In the formula F=m*a, m stands for:
mass
The unit m/s2 is used when talking about:
acceleration
When 1 object applies a force to another object, the 2nd object applies an equal and opposite force to the 1st object.
What is Newton's third law of motion?
When 2 objects collide, what kind of force do they exert on each other?
Equal and opposite
Wearing socks on the classroom floor reduces/increases friction.
Reduces
In the formula F=m*a, a stands for:
acceleration
The unit kilogram (kg) is used when talking about:
mass
