Collision Course Final Flashcard

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined. If the net force is zero, the object is in equilibrium.

Front

Why is the net force 0 when two elephants pull with equal force in opposite directions?

Back

Because they are both pulling the same amount of force in opposite directions.

Front

How do you calculate speed?

Back

Speed is calculated by dividing the distance traveled by the time taken. Formula: Speed = Distance / Time.

Front

What is the speed of an object that travels 20 meters in 4 seconds?

Back

5 m/s (Speed = 20 meters / 4 seconds).

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd Law states that Force equals Mass multiplied by Acceleration (F = m * a).

Front

What does Newton's 1st Law of Motion state?

Back

An object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by a net external force.

Front

What are constraints in project management?

Back

Constraints are limitations or restrictions that affect the project's scope, such as time, budget, and safety.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m * a).

Front

What is the relationship between mass and acceleration in Newton's 2nd Law?

Back

The greater the mass of an object, the more force is required to accelerate it.

Front

What is an example of a trade-off in project management?

Back

Choosing to spend more time on a project may improve quality but could exceed the budget.
