The rate of change of velocity of an object with respect to time
What is acceleration?
This equation can be used to find the time, if and only if the object has been launched horizontally.
t = sqrt(2y/g)
The tendency of an object to remain in its state of motion.
What is inertia?
Give an example of projectile motion in sports.
Examples of projectile motion in sports include a soccer ball being kicked or a basketball shot into the hoop.
The variable g represents this factor in projectile motion.
What is acceleration due to gravity?
A form of motion experienced by an object or particle that is thrown near the Earth's surface and moves along a curved path under the action of gravity only
What is Projectile Motion?
The variable V0 is used to represent the ______ velocity of a projectile.
What is initial?
The study of motion. Often involves graphs, such as a position time graph.
What is kinematics?
Explain how military applications utilize projectile motion principles.
Military applications use projectile motion principles to predict the range and impact point of missiles and artillery.
This trig ratio is used to determine the vertical component of velocity.
What is Sine?
If a projectile is launched at an angle of 30 degrees, what are its horizontal and vertical components?
Vx = v*cos30
Vy= v*sin30
When the variable g is portrayed in an equation, it usually represents acceleration due to gravity which is this number.
What is 9.8 m/s2?
A position time graph for an object that is speeding up.
What is a parabola?
A skateboarder rides off a ramp at an angle. What can they do to go farther in the air?
Go faster before leaving the ramp to increase their speed.
The variable Vx displays the _______ _______ along the x-axis
What is horizontal velocity?
A vector quantity that refers to "how far out of place an object is", this is the object's overall change in position.
What is displacement?
The equation x = vx t
What is horizontal distance or range?
Describe the difference between horizontal and vertical motion in projectile motion.
Horizontal motion is uniform (constant velocity), as there are no forces acting in the horizontal direction (ignoring air resistance). Vertical motion is uniformly accelerated motion due to the force of gravity.
In ancient warfare, catapults launched large rocks to break down enemy walls. If a rock is launched at the same speed but at two different angles—30° and 60°—which one will travel further?
Neither. Both angles produce the same range because they are complementary angles that add to 90°.
The variable t is used to represent this component of projectile motion.
What is time?
The angle (θ) at which a projectile is launched to reach the maximum range.
What is the 45 degree angle?
Given an initial velocity of 20 m/s at an angle of 45 degrees, find the time of flight. Give answer in 3 significant figures.
2.88s
An object that is accelerating must be experiencing a(n) ___ ___ according to Newton's 2nd Law of Motion.
What is net force or unbalanced force?
Imagine you are designing a stunt for a movie where a car drives off a ramp and jumps over a river. What factors do you need to consider to make sure the car lands safely on the other side, assuming no air resistance?
The car’s speed, launch angle, and landing height of the car.
The equation can be used to find a resultant, derived from a the philosopher, Pythagoras.
What is the Pythagorean theorem?
