- Q1an object thrown or launched through the air which is only under the influence of the force of gravity.A projectile is...30s
- Q2is the parabolic path that a projectile takes through the air.The trajectory of a projectile is...30s
- Q3only under influence of the force of gravity, and as a result experiences an acceleration due to gravity of 9.8 m/s^2 downward.An object in freefall is...30s
- Q4the highest point in the object's motion. At that point the vertical velocity of the object is zero.The apex of projectile's trajectory is...30s
- Q5None, the Horizontal and Vertical motions are independent of each other, i.e. what happens Horizontally does not affect the Vertical.What's the relationship between an object's Horizontal and Vertical motions?30s
- Q6the motion of an object that is left or right, or parallel to the ground.A Horizontal motion is...30s
- Q7the motion of an object that is up or down, or perpendicular (90 degrees) to the ground.A Vertical motion is...30s
- Q89.8 m/s^2 downWhat is the acceleration of an object in freefall on Earth?30s
- Q9'g' represents the constant 9.8 m/s^2, which is the acceleration due to gravity on the planet Earth.What does the variable 'g' represent?30s
- Q10Trick question - they'll hit at the same time. Without drag the Hammer and the Feather accelerate downwards at the same rate.If you drop a Hammer and a Feather in a vacuum at the same time from the same height, which will hit the ground first? (Vacuum is an area without an atmosphere, so there is no air resistance or drag)30s
- Q11Only the Force of Gravity is acting on the football.After a football has been thrown and is traveling to its target, what force(s) are acting on it?30s
- Q12The horizontal motion is constant because there are no horizontal forces acting on the football.After a football has been thrown and is traveling to its target, how would you describe its horizontal motion?30s
- Q13The vertical motion is changing due to force of gravity. So the football is accelerating downward at 9.8 m/s^2.After a football has been thrown and is traveling to its target, how would you describe its vertical motion?30s
- Q14The vertical velocity is zero at the apex, or the highest point when the football switches from traveling up to traveling down.After a football has been thrown and is traveling to its target, at what point is the vertical velocity zero?30s
- Q15The football is moving the fastest at the lowest point of the trajectory.After a football has been thrown and is traveling to its target, when is the football moving the fastest?30s
