Question

Is a projectile motion graph a straight graph or a curved graph
​

Answer 1

» Projectile motion is a curved graph.

☑ This is because projectile motion consists of both vertical and horizontal motion, with one starting angle. Hence as the body starts motion, it is acted upon by gravity.

At point v = 0, the motion is free from gravity hence approaching horizontal motion.

Examples;

• A ball kicked upwards at an angle which is not 90°
• A man playing golf.
• A plane dropping a bomb.

Answer 2

Hi there!

Curved graph.

For an object undergoing projectile motion, the HORIZONTAL component of its remains constant (assuming no air resistance), while the VERTICAL component is changing due to a constant acceleration due to gravity.

We can relate vertical displacement vs. time to this acceleration using the kinematic equation:

`d_y= v_(y0)t + (1)/(2)at^2`

dy = displacement (m)

vy₀ = initial vertical velocity (m/s)

t = time (s)

a = acceleration due to gravity (m/s²)

This is an example of a QUADRATIC equation, which means the trajectory of a projectile would form a parabolic shape.

Thus, it would be a curved graph.
