What is the best material for building a boat that can speed up and slow down quickly?

Back

Aluminum is the best material because it is lightweight and has a high strength-to-weight ratio, allowing for quick acceleration and deceleration.

What does the graph of force vs. mass look like when acceleration is constant?

Back

The graph is a straight line, indicating that force is directly proportional to mass when acceleration is constant.

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, typically measured in meters per second squared (m/s²).

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, force equals mass times acceleration (F = ma).

Front

What happens to the acceleration of an object if the mass increases while the force remains constant?

Back

The acceleration decreases because acceleration is inversely proportional to mass when force is constant.

What is the effect of friction on the motion of an object?

Back

Friction opposes the motion of an object, making it harder to start moving or to keep moving.

Front

What is the definition of mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms (kg).
