Physics Quiz: Introduction To Motion! Trivia Questions

The correct answer is "Quantity having both a size (far, fast) and a direction (left or right, north or south ext)." This answer accurately describes a vector quantity. Vector quantities are physical quantities that have both magnitude (size or value) and direction. Examples of vector quantities include displacement, velocity, and force.

The correct answer is that a Position vs Time graph has a continuous line or curve showing an object's position as a function of time. This means that the graph represents how the position of the object changes over time. The x-axis represents time, while the y-axis represents the object's position. By looking at the graph, one can determine how the object's position changes at different points in time.

The correct answer is (change of velocity)/ (time interval). Average acceleration is defined as the change in velocity divided by the time interval. It measures how quickly the velocity of an object changes over a given period of time. By calculating the difference in velocity and dividing it by the time interval, we can determine the average rate at which the velocity is changing.

The correct answer is "Change of an object's position with time." This answer accurately describes motion as the movement or displacement of an object over a period of time. It emphasizes the relationship between an object's position and the change it undergoes as time progresses. This definition encompasses both straight and curved paths that an object may follow during its motion.

Average velocity is defined as the displacement or change in position divided by the time interval. This means that to calculate average velocity, we need to divide the distance traveled by the time it took to travel that distance. Therefore, the correct answer is (distance) / (time interval).

The correct answer is "an object represented as a mass at a single point" because a particle is a term used in physics to refer to an object that is treated as having a negligible size or shape, and is represented as a mass concentrated at a single point. This simplification allows for easier calculations and analysis of the object's motion and interactions with other particles.

The correct answer is "motion of an object by displaying its location at various equally spaced times on the same diagram." This answer accurately describes a motion diagram, which is a visual representation of an object's motion. It involves plotting the object's position at different points in time on the same diagram, typically using arrows or dots. This allows for the observation of the object's trajectory and any changes in its position over time.

The correct answer is "Physical quantity described by a single number (with unit)." This is because a scalar quantity is a type of physical quantity that can be described by a single number and does not have a direction associated with it. Examples of scalar quantities include mass, temperature, and time.

The correct answer is "Path along which an object moves; straight or curve". This is because a trajectory refers to the path that an object follows as it moves through space. It can be a straight line or a curved line, depending on the motion of the object.

The correct answer is "Motion of an object represented as a mass concentrated at a single point". This answer accurately describes the particle model, which is a simplification of real-world objects where their motion is represented as a single point mass. This model allows for easier analysis and calculations of the object's motion without considering its size or shape.

The position vector is represented as an arrow drawn from the origin to an object's position. This vector indicates both the magnitude and direction of the object's displacement from the origin. It is commonly used in physics and mathematics to describe the position of an object in a coordinate system.

The correct answer is "Change of position." Displacement refers to the change in position of an object over a certain period of time. It is a vector quantity that indicates both the magnitude and direction of the change in position. This term is often used in physics to describe the motion of an object, as it focuses on how the object's position has changed rather than the specific path it took to get there.

The correct answer is "Motion of an object along a trajectory." This is because translational motion refers to the movement of an object in a straight line or along a curved path, known as a trajectory. The other options do not accurately describe translational motion.

This question is asking for the steps involved in creating a pictorial representation. The correct answer includes drawing a motion diagram, establishing a coordinate system, sketching the situation, defining symbols, and listing known information and identifying the desired unknowns. These steps are all necessary in order to accurately represent a situation visually.

The number .0020 has two significant figures because the zeros before the 2 are not significant. The number 6.20 has three significant figures because all the digits are significant. The number 0.0 has two significant figures because the zero after the decimal point is not significant.
