Front

What shape does a projectile make?

Back

Parabola

Front

If a rock takes 5 seconds to reach point D, how long will it take to reach the ground from point D?

Back

5 s

Front

What is the 'magnitude' of a vector?

Back

The length of the vector shows magnitude.

Front

What do the north-south axis and east-west axis provide?

Back

A reference line.

Front

Vectors in two dimensions are ___________

Back

Independent.

Front

What is the definition of a projectile?

Back

An object that is thrown into the air with an initial velocity.

Front

What factors affect the trajectory of a projectile?

Back

Initial velocity, angle of launch, and acceleration due to gravity.

Front

What is the formula for the range of a projectile?

Back

Range = (v^2 * sin(2θ)) / g, where v is initial velocity, θ is launch angle, and g is acceleration due to gravity.

Front

What is the difference between scalar and vector quantities?

Back

Scalars have magnitude only, while vectors have both magnitude and direction.

Front

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

Back

It determines the maximum height and range of the projectile.
