What Describes An Object In Projectile Motion Select 3? Gravity acts to pull the object down. The object moves in a straight path. The forward velocity of the object is 0 m/s. The object’s inertia carries it forward. What are the 3 main concepts of projectile motion? Key Points: Range, Symmetry, Maximum Height. Projectile motion
What Happened To The Ball That Was Kicked Upward After It Reached Its Highest Point? Variable Value Δy FIND a -9.8 m/s2 t 0.40 s When you throw a ball vertically upward at its highest point of motion? When a body is thrown vertically upwards, at the highest point_____ (both velocity and acceleration are zero/only
How Do You Find The Speed Of A Projectile When It Hits The Ground? the speed of the object when hits the ground is the velocity at time t∗, where t∗ is the value of t when s(t)=sG=0 (if your reference system is placed at s=sG=0 for the ground). How do you find the speed
How High Into The Air Did The Ball Travel? Use the vertical motion model, h = -16t2 + vt + s, where v is the initial velocity in feet/second and s is the height in feet, to calculate the maximum height of the ball. How high did the ball travel h in meters? h =
Do Projectiles Have A Predictable Path? Do projectiles have a predictable path? Projectile motion Is projectile motion predictable? The trajectory of an object undergoing projectile motion is predictable. The object will follow a parabolic path that depends only on the initial conditions (launch angle and initial velocity) and acceleration due to gravity: Trajectories of projectiles
