What is Projectile Motion?

Projectile Motion describes the path of an object launched into the air that is subject only to gravity. The path is typically a parabola.

To understand the forces acting on the projectile, check out our Forces & Newton's Laws Calculator.

To calculate velocity and acceleration in one dimension, use our Kinematics Motion Calculator.

To analyze the energy changes during flight, explore our Work–Energy–Power Calculator.

Formulas Used

  • Vx = v₀ * cos(θ)
  • Vy = v₀ * sin(θ)
  • Time = (2 * Vy) / g (if h₀=0)
  • Height = h₀ + (Vy²) / (2g)
  • Range = Vx * Time

Key Concepts

  • Parabolic Trajectory: Objects follow a curved parabolic path under gravity.
  • Independence of Motion: Horizontal and vertical motions are independent.
  • Symmetry: Time up equals time down for same height launch and landing.

How to Use

1

Enter Velocity

Input initial speed in m/s.

2

Enter Angle

Input launch angle in degrees.

3

Benefits of Using This Calculator

  • Quick Results: Instant calculations for complex trajectory problems.
  • Multiple Parameters: Get range, max height, time, and velocity components.
  • Educational Tool: Perfect for physics students and educators.

Factors Affecting Range

  • Launch Angle: 45° gives max range in vacuum.
  • Initial Speed: Range increases with the square of speed.
  • Gravity: Higher gravity reduces range and height.
  • Initial Height: Higher starting position increases range.

Frequently Asked Questions (FAQ)

Q: What is projectile motion?

A: Projectile motion is a form of motion experienced by an object or particle that is projected near the Earth's surface and moves along a curved path under the action of gravity only.

Q: What assumptions are made?

A: This calculator assumes negligible air resistance and a constant acceleration due to gravity (g = 9.81 m/s²) acting downwards.

Q: What is the maximum range angle?

A: In ideal conditions (no air resistance), the maximum range is achieved at a launch angle of 45 degrees.
