Unit 3 - Two-Dimensional Motion: Activity 1 (Flashcardizz)

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is the velocity of a projectile at its maximum height?

Back

0 m/s

Front

What is the vertical component of a projectile's velocity if it is 26 m/s?

Back

26 m/s

Front

How do you calculate the horizontal component of a projectile's velocity?

Back

Use the formula: Vx = V * cos(θ), where V is the initial velocity and θ is the angle.

Front

What is the horizontal component of a soccer ball kicked at a 36 degree angle with a velocity of 23 m/s?

Back

18.6 m/s

Front

How does friction affect the speed of an object?

Back

More friction decreases speed.

Front

What is the formula for calculating the range of a projectile?

Back

Range = (V^2 * 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 acceleration due to gravity on Earth?

Back

Approximately 9.81 m/s².

Front

What is the difference between scalar and vector quantities?

Back

Scalar quantities have magnitude only, while vector quantities have both magnitude and direction.

Front

What is the formula for calculating the time of flight of a projectile?

Back

Time of flight = (2 * V * sin(θ)) / g.
