What is projectile motion?

Back

Projectile motion is the motion of an object that is thrown into the air and is subject to the force of gravity. It follows a curved path called a trajectory.

Front

What are the two components of projectile motion?

Back

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

Front

What is the acceleration due to gravity?

Back

The acceleration due to gravity is approximately 9.8 m/s² downward.

Front

At what point does a projectile reach its maximum height?

Back

A projectile reaches its maximum height at the peak of its trajectory, where its vertical velocity is zero.

Front

What is the direction of the velocity of a projectile at its maximum height?

Back

At maximum height, the vertical component of velocity is zero, but the horizontal component remains constant.

Front

How does the horizontal motion of a projectile differ from its vertical motion?

Back

Horizontal motion is uniform (constant velocity), while vertical motion is influenced by gravity (accelerated motion).

Front

What factors affect the range of a projectile?

Back

The range of a projectile is affected by its initial velocity, launch angle, and the height from which it is launched.

Front

What is the formula for the range of a projectile launched at an angle?

Back

The range R can be calculated using the formula 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 happens to the time of flight if the launch angle is increased?

Back

Increasing the launch angle generally increases the time of flight, up to a maximum at 45 degrees.

Front

What is the trajectory of a projectile?

Back

The trajectory of a projectile is the path it follows through space, typically a parabolic shape.
