2D Motion - Summative

Front

What is the definition of 2D motion?

Back

2D motion refers to the movement of an object in a two-dimensional plane, characterized by both horizontal and vertical components.

Front

What is the formula for calculating the horizontal component of velocity?

Back

The horizontal component of velocity (Vx) can be calculated using the formula: Vx = V * cos(θ), where V is the total velocity and θ is the angle of projection.

Front

What is the formula for calculating the vertical component of velocity?

Back

The vertical component of velocity (Vy) can be calculated using the formula: Vy = V * sin(θ), where V is the total velocity and θ is the angle of projection.

Front

What is the acceleration due to gravity?

Back

The acceleration due to gravity (g) is approximately -9.8 m/s², acting downwards towards the center of the Earth.

Front

What is a projectile?

Back

A projectile is an object that is launched into the air and is subject to the force of gravity and air resistance.

Front

What is the horizontal acceleration of a projectile?

Back

The horizontal acceleration of a projectile is 0 m/s², as there are no horizontal forces acting on it (ignoring air resistance).

Front

What is the vertical acceleration of a projectile at its peak height?

Back

The vertical acceleration of a projectile is -9.8 m/s² at all points in its trajectory, including at its peak height.

Front

How do you calculate the range of a projectile?

Back

The range (R) of a projectile can be calculated using the formula: R = (V^2 * sin(2θ)) / g, where V is the initial velocity, θ is the angle of projection, and g is the acceleration due to gravity.

Front

What is the time of flight for a projectile?

Back

The time of flight (T) can be calculated using the formula: T = (2V * sin(θ)) / g, where V is the initial velocity and θ is the angle of projection.

Front

What is the difference between scalar and vector quantities?

Back

Scalar quantities have only magnitude (e.g., speed), while vector quantities have both magnitude and direction (e.g., velocity).
