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

Front

What is the formula to find velocity in linear motion?

Back

v = d/t

Front

What is the attractive force that exists between all objects that have mass?

Back

Gravity

Front

State Newton's 3rd Law of Motion.

Back

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

Front

What happens when two objects exert equal forces on each other?

Back

They will not move at all.

Front

What is the time of flight for a cannonball fired at a 45.0° angle with an initial velocity of 625 m/s (ignoring air resistance)?

Back

90.2 s

Front

Define projectile motion.

Back

Projectile motion is the motion of an object thrown into the air, subject to only the acceleration of gravity.

Front

What is the horizontal component of velocity in projectile motion?

Back

It remains constant throughout the motion.

Front

What is the vertical component of velocity in projectile motion?

Back

It changes due to the acceleration of gravity.

Front

What is the acceleration due to gravity on Earth?

Back

Approximately 9.81 m/s².

Front

How do you calculate the range of a projectile?

Back

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