Physics

Kinematics equations are used to analyze objects that rest/move at …..

Accelerate uniformity

When setting up a kinematic, how many known motion parameters do you need to know to solve for the unknown

3

If an object starting from rest accelerates at +5 m/s?. What happens to the velocity of the object as time passes?

Velocity increase by 5 m/s each second

an object is dropped or tossed upward it is said to be in free-fall. Free-fall is when only_ acts on an object.

Gravity

5) The acceleration due to ____

for an object in free fall is _____?

Gravity; -9.8m/s²

What does Vi stand for

Initial velocity (m/s)

What does Vf stand for?

Final velocity (m/s)

what does a stand for?

Acceleration; (m/s²)

What does t stand for?

Time ; (s)

What does ДХ stand for?

Displacement; (m)

(True or false) An object in free fall is affected by only gravity.

True

(True or false) For an upward thrown object, the greatest velocity is at the top of the trajectory?

False

(True or False) If the velocity and the acceleration are in the same direction the object slows down

False

(True or False) . An upward thrown object may have an initial velocity of 0 m/s.

False

(True or False) If a coin is tossed into the air it takes the same amount of time to rise to the max position as it does to fall from max position to point of release (time for the upward part of motion is the same as the time to fall).

True

What is Free Fall

An object that falls solely on the force of gravity.
