2 Dimensional Motion

What is projectile motion?

• Circular motion

• Linear motion under gravity

• Motion of an object thrown into the air with horizontal and vertical components

• Rotational motion

Why is the horizontal velocity of a projectile constant?

• Gravity acts horizontally

• No horizontal forces act on it

• Air resistance increases horizontal velocity

• The vertical motion cancels the horizontal motion

What determines the time of flight for a projectile?

• Horizontal velocity

• Vertical motion

• Air resistance

• Launch angle

What is the trajectory of a projectile?

• A straight line

• A circle

• A parabola

• A hyperbola

In projectile motion, what is the value of vertical velocity at the maximum height?

• Zero

• Maximum

• Same as horizontal velocity

• Depends on the initial angle

What determines the horizontal range of a projectile?

• The initial vertical velocity only

• The initial horizontal velocity and time of flight

• The angle of projection only

• Gravity alone

What type of acceleration acts on a projectile during its motion?

• Horizontal acceleration only

• Vertical acceleration only

• Both horizontal and vertical acceleration

• No acceleration acts on a projectile
