Projectile Motion

Front

What is projectile motion?

Back

Projectile motion is the motion of an object thrown into the air, subject to the force of gravity, following a curved path called a trajectory.

Front

What are the two components of projectile motion?

Back

The two components are horizontal motion (constant velocity) and vertical motion (accelerated motion due to gravity).

Front

Does horizontal velocity change if you ignore air resistance?

Back

No, horizontal velocity remains constant in the absence of air resistance.

Front

What is the acceleration due to gravity near the Earth's surface?

Back

The acceleration due to gravity is approximately 9.81 m/s².

Front

What is the formula for calculating the range of a projectile?

Back

Range (R) = (v₀² * sin(2θ)) / g, where v₀ is the initial velocity, θ is the launch angle, and g is the acceleration due to gravity.

Front

What is the significance of the launch angle in projectile motion?

Back

The launch angle determines the shape of the trajectory and affects the range and maximum height of the projectile.

Front

What happens to vertical velocity as a projectile rises?

Back

Vertical velocity decreases as the projectile rises until it reaches its highest point.

Front

What happens to vertical velocity as a projectile falls?

Back

Vertical velocity increases as the projectile falls due to the acceleration of gravity.

Front

What is the vertical velocity at the highest point of a projectile's trajectory?

Back

The vertical velocity is 0 m/s at the highest point of the trajectory.

Front

What is the relationship between time of flight and vertical motion?

Back

The time of flight is determined by the vertical motion and is influenced by the initial vertical velocity and acceleration due to gravity.
