Projectile Motion

Front

What is the optimal angle for maximum range in projectile motion?

Back

45°

Front

What is the horizontal acceleration of a projectile when air resistance is neglected?

Back

0 m/s²

Front

What does the variable 't' represent in projectile motion equations?

Back

Time

Front

What variable letter is used to denote range or horizontal displacement in projectile motion?

Back

dₓ

Front

What variable letter is used to denote altitude or height in projectile motion?

Back

dᵧ

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 effect of increasing the launch angle beyond 45° on the range of a projectile?

Back

The range decreases.

Front

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

Back

The time of flight is directly related to the vertical displacement and can be calculated using the formula: t = (2 * v₀ * sin(θ)) / g.

Front

How does air resistance affect the range of a projectile?

Back

Air resistance decreases the range of a projectile compared to the ideal case without air resistance.

Front

What is the significance of the initial velocity in projectile motion?

Back

The initial velocity determines both the range and the maximum height of the projectile.
