What is Velocity?
Force opposite motion on a surface.
What is Friction?
Vertical velocity at top of trajectory
What is zero?
What is the acceleration formula?
a=(Vf-Vi)/t
the acceleration due to gravity
What is 9.8 m/s2
Ball dropped from rest. Distance in 3 s
What is 44.1 m?
Reason of why when a hammer and a feather are dropped at the same time on the moon reach the ground at the same time.

What are the forces acting on a ball thrown into the air
What are air resistance and gravity?
This is the formula to calculate Speed
What is distance ÷ time?
What is the definition of static equilibrium
What is an object at rest?
Acceleration of a Runner when she goes from 2 m/s to 8 m/s in 3 s.
What is 2 m/s2.
The Inventor of US Patent 5 567 747.
Who is Mr. Rizopoulos?
Time to ground when a Ball launched horizontally at 10 m/s from 20 m cliff.
What is 2.02?
The difference between Scalar and vector.
In acceleration formula, what does Vi stand for?
What is Initial Velocity?
A gun is fired directly into the sky, what would the velocity of the bullet be when it reaches it's maximum height?
What is 0 m/s?
A 15 kg block on 30° incline. Parallel component of gravity.
What is 73.5 N? F∥=mgsinθ=15⋅9.8⋅0.5=73.5 N
Initial vertical velocity of a projectile launched at 20 m/s at 30°.
What is 10 m/s?
What does the second law of newton indicate?
The force of an object is equal to the mass times the acceleration of the object, or, the acceleration of an object is equal to the force divided by the mass.
A 1.0 × 103 -kilogram car travels at a constant speed of 20 meters per second around a horizontal circular track. The diameter of the track is 1.0 × 102 meters. The magnitude of the car’s centripetal acceleration is
What is 8 m/s2?
The distance a car traveled if it drove at 40 m/s for 30 minutes.
What is 72 000 m?
The net force when a 10 kg block pulled with 50 N and the coefficient of friction is 0.20 on a horizontal surface.
What is 30 N?
Time to max height when a Ball launched at 15 m/s at 45°.
What is 1.08s?
Tyler runs the basketball court 5 times back and forth. Tyler's displacement is
What is 0 meters? He ended where he started
Name the three laws of motion stated by Isaac Newton
*First law: Every object in rest will remain that way until an external force acts upon it, and every object in movement will stay that way until an external force acts upon it (intertia law).
*Second Law: The Force of an object is equal to the mass of the object times the acceleration.
*Third law: for every action there's an equal reaction in magnitude and in the oposite direction
