Spring 2024 Final Exam Review Pt. 3

Front

What is displacement in physics?

Back

Displacement is the vector quantity that refers to the change in position of an object. It is defined as the shortest distance from the initial to the final position, along with the direction.

Front

How do you calculate displacement when given velocity and time?

Back

Displacement can be calculated using the formula: Displacement = Velocity × Time. This gives the total distance covered in a specific direction.

Front

What does a constant speed on a graph indicate?

Back

A constant speed on a graph indicates that the object is moving at the same rate over time, represented by a straight line with a constant slope.

Front

What is the most chemically reactive element among beryllium, calcium, strontium, and radium?

Back

Radium (Ra) is the most chemically reactive element among these options.

Front

What are ionic bonds?

Back

Ionic bonds are chemical bonds formed through the electrostatic attraction between oppositely charged ions, typically between metals and nonmetals.

Front

Which compound contains ionic bonds: C2H6, PCl5, Ca3N2, or SF2?

Back

Ca3N2 contains ionic bonds.

Front

What happens to an object's mass and weight when taken into outer space?

Back

The mass remains the same, but the weight decreases due to the reduced gravitational pull in outer space.

Front

Define velocity in physics.

Back

Velocity is a vector quantity that refers to the rate at which an object changes its position, including both speed and direction.

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 includes both speed and direction.

Front

What is the formula for calculating weight?

Back

Weight can be calculated using the formula: Weight = Mass × Gravitational Acceleration (W = m × g).
