Newtons laws
What is Newton's first law?
The law of inertia.
What is the equation for distance?
Distance= Velocity x time.
If you set one small book and one big book on the floor which one will be easier to push across the floor?
The small book will be easier to push.
What is acceleration?
Acceleration is a change in speed or direction.
What is a reference point?
A place or object that determines if something is in motion.
What is Newton's third law.
The third law is the law of action and reaction.
What is the equation for speed?
Distance/time
What is rolling friction?
Rolling friction is when wheels are on an object so it moves easier.
What is the equation for acceleration?
vf-vi/time.
Another name for unbalanced force?
Net Force
What is Newton's second law?
The law of force and acceleration.
What is the equation for Velocity?
Distance in direction/ time
What is sliding friction?
The friction that causes an object to stop.
should the direction of movement be included in the acceleration
The direction does not have to be included in acceleration.
What is another name for balanced force?
Stationary
What will happen to an object that is in motion.
The object will stay in motion until acted on by another force.
What is the equation for momentum?
Mass X Velocity (p=mXv)
What is fluid friction?
When sliding friction is replaced with liquid.
is acceleration a increase or decrease in speed.
Acceleration is andy change in speed.
If Ellie runs 100 meters in 17 seconds how fast is she running?
5.882 meters per second
Which of Newton's laws is about Force.
The second law is about force.
A car traveled 180 miles at 60 mph how long did it take to reach the destination?
3 hours
What is static friction?
When force is applied to an object and the object doesn't move.
How is it possible to change acceleration and stay at the same speed?
Changing direction
they will both hit the ground at the same time.
