Semester Review (Physics)

Front

What is the relationship between distance and gravity as two objects get closer together?

Back

The force of gravity increases as the distance between two objects decreases.

Front

What does a velocity-time graph represent?

Back

A velocity-time graph shows how the velocity of an object changes over time.

Front

What is negative acceleration?

Back

Negative acceleration occurs when an object is slowing down.

Front

In circular motion, which quantity is not constant?

Back

Velocity is not constant in circular motion because the direction of the velocity vector changes.

Front

How do you convert decimeters per week to kilometers per year?

Back

To convert, multiply by the conversion factors: 1 dm = 0.0001 km and 1 year = 52 weeks.

Front

What is the formula for gravitational force between two objects?

Back

F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers.

Front

What is constant velocity?

Back

Constant velocity means an object is moving at a steady speed in a straight line.

Front

What is the significance of the slope in a velocity-time graph?

Back

The slope of a velocity-time graph represents acceleration.

Front

What happens to the gravitational force if the mass of one object increases?

Back

The gravitational force increases if the mass of one object increases.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).
