Front

What is Newton's second law of motion?

Back

Newton's second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. It can be expressed with the formula: F = ma, where F is the net force, m is the mass, and a is the acceleration.

How do you express 3,400 in scientific notation?

Back

3,400 in scientific notation is expressed as 3.4 x 10^3.

Front

What happens to two objects dropped from the same height in a vacuum?

Back

In a vacuum, both objects will hit the ground at the same time regardless of their mass, demonstrating that the acceleration due to gravity is constant.

Front

What does Kepler's Second Law state about a planet's speed as it orbits the Sun?

Back

Kepler's Second Law states that a planet's speed increases as it moves closer to the Sun and decreases as it moves further away.

Front

How can you determine instantaneous speed from a position-time graph?

Back

The instantaneous speed can be determined by finding the slope of the tangent line to the curve at the desired time on the position-time graph.

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = ma, where F is force, m is mass, and a is acceleration.

Front

What is the law of universal gravitation?

Back

The law of universal gravitation states that every point mass attracts every other point mass in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both the speed and direction of the object's motion.

Front

What is inertia?

Back

Inertia is the property of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

What is the formula for calculating kinetic energy?

Back

The formula for calculating kinetic energy is KE = \frac{1}{2}mv^2, where KE is kinetic energy, m is mass, and v is velocity.
