What is the difference between kinematics in one dimension and kinematics in two dimensions?
Kinematics in one dimension focuses on motion in a straight line, while kinematics in two dimensions involves motion in two perpendicular directions.
What are the two components of velocity in two dimensions?
The horizontal component and the vertical component.
What are the equations used to solve problems in two-dimensional kinematics?
The equations of motion in the x-direction and the y-direction.
What is projectile motion?
The motion of an object projected into the air at an angle.
How can you calculate the time of flight for projectile motion?
By using the vertical component of velocity and the acceleration due to gravity.
What is the range of a projectile?
The horizontal distance traveled by a projectile before it hits the ground.
What is the equation for range in projectile motion?
Range = (horizontal component of initial velocity) * (time of flight).
What is the equation for maximum height in projectile motion?
Maximum height = (vertical component of initial velocity)^2 / (2 * acceleration due to gravity).
What are some real-life examples of motion in two dimensions?
Ball being thrown in the air, fireworks launched into the sky.
Which of the following is true about motion in two dimensions?
A) The horizontal and vertical motions are independent of each other. B) The displacement in each direction can be calculated separately. C) The acceleration in each direction can be determined independently. D) All of the above.
What happens to the horizontal velocity of a projectile during its flight?
It remains constant.
What happens to the vertical velocity of a projectile during its flight?
It changes due to the acceleration due to gravity.
What is the shape of the trajectory followed by a projectile?
A parabola.
How can you determine the displacement of a projectile at any given time?
By adding the displacements in the horizontal and vertical directions separately.
