Newtons Laws
What is Newton's 3rd law?
For every action there is an equal and opposite reaction.
Define velocity
The rate of change of an objects position with respect to time, representing both its speed and direction of motion.
Define Gravity
The force pulling objects down and is responsible for keeping objects on the ground
Is this an example of friction?
You slide across ice without slowing down.
No
What are some examples of how distance is measured?
Cm, M, In, Ft, Yds
What is Newton's 1st law?
An object at rest will stay at rest and an object in motion will stay in motion unless acted upon by an unbalanced, external force.
What is Newtons 2nd law?
Force = Mass x Acceleration
What is the difference between speed and acceleration?
Speed is how an object is moving and acceleration involves distance.
What is force?
A push or a pull that changes an objects speed, direction, or shape.
which example has more friction?
a bowling ball rolling on a bowling lane or a car driving on a gravel road
the car driving on a gravel road
how long will it take you to travel 150 miles at a speed of 8 miles an hour
18.75 mph
What law is this an example of?
A bowling ball requires more force to travel fast than a tennis ball.
Newtons 2nd law
What law is this an example of?
A probe in deep space keeps moving without needing fuel, as there is no friction to stop it.
Newtons 1st law
How do you calculate speed?
Speed = Distance / Time
Is this an example of a force or gravity?
Throwing a ball in the air
Force
define friction
the force that opposes the relative motion between two surfaces
if you are traveling 70 mph how long will it take you to travel 1,190 miles
17 hours
