Projectile Motion

Front

What are the components of a vector?

Back

A vector has both magnitude and direction, typically represented by its components along the coordinate axes, such as North and East.

Front

What is the velocity of an object at the highest point of its trajectory when thrown straight up?

Back

0 m/s

Front

If a crayon is thrown straight up at 12 m/s, what is its speed when caught at the same height?

Back

-12 m/s

Front

What is the difference between velocity and speed?

Back

Velocity is speed in a given direction, while speed is the magnitude of movement without direction.

Front

What is the acceleration of an object at the highest point of its trajectory when thrown straight up?

Back

-9.8 m/s² (due to gravity).

Front

Define projectile motion.

Back

Projectile motion is the motion of an object thrown into the air, subject to gravitational acceleration and air resistance.

Front

What factors affect the range of a projectile?

Back

The initial velocity, launch angle, and height of launch affect the range of a projectile.

Front

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

Back

Range (R) = (v² * sin(2θ)) / g, where v is the initial velocity, θ is the launch angle, and g is the acceleration due to gravity.

Front

What is the effect of air resistance on projectile motion?

Back

Air resistance reduces the range and height of a projectile compared to ideal conditions without air resistance.

Front

How does the launch angle affect the maximum height of a projectile?

Back

A launch angle of 90° gives the maximum height, while angles less than 90° decrease the height.
