What is projectile motion?

• Projectile motion is the motion of an object that defies the laws of physics and moves randomly in space.

• Projectile motion is the motion of an object moving in a straight line without any external forces acting on it.

• Projectile motion is the motion of an object thrown or projected into the air, subject to gravity and air resistance. It follows a curved path known as a trajectory.

• Projectile motion is the motion of an object that travels faster than the speed of light.

Explain the concept of trajectory in projectile motion.

• The trajectory in projectile motion is the curved path followed by the object as it moves through the air.

• The trajectory is a straight line

• The trajectory is a circle

• The trajectory is a random pattern

How does the angle of projection affect the range of a projectile?

• Decreasing the angle of projection increases the range of a projectile.

• The angle of projection affects the range of a projectile by changing the vertical and horizontal components of the initial velocity.

• The angle of projection has no effect on the range of a projectile.

• Increasing the angle of projection decreases the range of a projectile.

Define the terms 'horizontal velocity' and 'vertical velocity' in projectile motion.

• Horizontal velocity changes due to gravity in projectile motion.

• Vertical velocity is independent of gravity in projectile motion.

• Horizontal velocity is constant in projectile motion, while vertical velocity changes due to gravity.

• Horizontal velocity increases with time in projectile motion.

What is the formula to calculate the time of flight for a projectile?

• time of flight = (initial velocity * sin(angle of projection)) * acceleration due to gravity

• time of flight = 2 * (initial velocity * sin(angle of projection)) / acceleration due to gravity

• time of flight = (initial velocity * sin(angle of projection)) / acceleration due to gravity

• time of flight = 2 * (initial velocity * cos(angle of projection)) / acceleration due to gravity

Discuss the factors affecting the maximum height attained by a projectile.

• Projectile weight, shoe size of the thrower, distance from the equator

• Projectile shape, favorite food of the thrower, temperature of the launch site

• Wind speed, color of the projectile, time of day

• Initial velocity, angle of projection, acceleration due to gravity, and air resistance.

Explain the difference between range and maximum height in projectile motion.

• Range is the total distance traveled, while maximum height is the initial height.

• Range is the time taken to reach the highest point, while maximum height is the time taken to reach the farthest point.

• Range is the horizontal distance, while maximum height is the vertical distance.

• Range is the vertical distance, while maximum height is the horizontal distance.

How can you determine the range of a projectile launched at an angle?

• Range = (velocity^2 * sin(2*angle)) / gravity

• Range = (velocity * sin(angle)) / gravity

• Range = (velocity^2 * cos(angle)) / gravity

• Range = (velocity^2 * sin(angle)) * gravity

What is the relationship between the horizontal and vertical components of velocity in projectile motion?

• The horizontal and vertical components of velocity are always equal in projectile motion.

• The vertical component of velocity is constant, and the horizontal component changes due to gravity.

• The horizontal component of velocity is constant, and the vertical component changes due to gravity.

• The horizontal component of velocity is greater than the vertical component.
