Questions #1

100

What factors determine the range of a projectile 

What is Air Resistance?

200

How does the projection angle affect the projectile motion?

What is it influences the object's trajectory and the maximum height it reaches?

300

Explain the relationship between initial velocity and projectile motion.

What is its magnitude decreases when an object travels upwards and increases when it travels downwards?

400

Define the term "projectile motion"

What is the motion of an object thrown or projected into the air, subject only to the acceleration of gravity?

500

What role does gravity play in projectile motion?

What is It determines how far and for how long an object can stay in air?

Questions #2

100

How does air resistance impact the motion of a projectile?

What is 

It slows down the speed of a projectile, causing it to reach a lower height and shorter horizontal distance than it would in a vacuum?

200

Describe the horizontal ad vertical components of projectile motion.

What is there are two simultaneous independent rectilinear motions: Along the x-axis: uniform velocity, responsible for the horizontal (forward) motion of the particle. Along the y-axis: uniform acceleration, responsible for the vertical (downwards) motion of the particle.

300

What is the significance of the time of flight in projectile motion

What is Time of flight refers to the time for which a particle is in air during the projectile motion?

400

Explain how range and maximum height are related in projectile motion.

What is The object's maximum height is the highest vertical position along its trajectory?

500

Discuss the impact of changing the initial velocity on a projectile trajectory.

What is The greater the initial speed v0, the greater the range for a given initial angle.

Questions #3

100

Acceleration when something is thrown upwards.

-9.8 m/s²

200

The formula for finding initial velocity

What is u=(v-at)

300

Formula for finding initial horizontal velocity

What is Vo=D/t

400

Formula for acceleration

What is a=v-vo/t

500

Formula for velocity

What is d/t=v

Questions #4

100

Definition of acceleration 

What is The rate of change of velocity with respect to time?

200

What is the definition of centripetal force?

What is a force that acts on a body moving in a circular path and is directed toward the center around which the body is moving?

300

What is the definition of centrifugal force?

What is an apparent force that acts outward on a body moving around a center, arising from the body's inertia?

400

Equation of centripetal acceleration

What is a_c = v²/r

500

What is the equation of centripetal force?

What is F_c=mv²/r
