Projectile Motion & Components

Front

What is projectile motion?

Back

Projectile motion is the motion of an object that is thrown into the air and is subject to the force of gravity. It follows a curved path called a trajectory.

Front

What are the two components of projectile motion?

Back

The two components of projectile motion are horizontal motion and vertical motion. They can be analyzed separately.

Front

What is the formula for the vertical component of velocity (Vy) in projectile motion?

Back

Vy = V sin(θ), where V is the initial velocity and θ is the angle of projection.

Front

What is the formula for the horizontal component of velocity (Vx) in projectile motion?

Back

Vx = V cos(θ), where V is the initial velocity and θ is the angle of projection.

Front

What does the term 'range' refer to in projectile motion?

Back

The range is the horizontal distance traveled by the projectile before it returns to the same vertical level from which it was launched.

Front

What is the effect of air resistance on projectile motion?

Back

Air resistance opposes the motion of the projectile, reducing its range and altering its trajectory.

Front

How does the angle of projection affect the range of a projectile?

Back

The optimal angle for maximum range in projectile motion is 45 degrees, assuming no air resistance.

Front

What is the acceleration due to gravity (g) near the Earth's surface?

Back

The acceleration due to gravity (g) is approximately 9.81 m/s².

Front

What is the significance of the normal force on an incline?

Back

The normal force is the force exerted by a surface that supports the weight of an object resting on it, acting perpendicular to the surface.

Front

How do you calculate the normal force on an incline?

Back

The normal force (N) on an incline is calculated as N = mg cos(θ), where m is mass, g is acceleration due to gravity, and θ is the angle of the incline.
