Define one-dimensional motion.
Motion along a straight line, characterized by position, velocity, and acceleration.
What does displacement measure?
The change in position of an object in a specific direction.
True or false: Speed is a vector quantity.
FALSE
Speed only has magnitude, while velocity includes direction.
Fill in the blank: Velocity is the rate of change of ______.
displacement
What is the formula for average speed?
Total distance traveled divided by total time taken.
Define acceleration.
The rate of change of velocity over time.
True or false: Acceleration can be negative.
TRUE
Negative acceleration is also known as deceleration.
What is uniform motion?
Motion at a constant speed in a straight line.
Fill in the blank: The slope of a distance-time graph represents ______.
speed
What does a velocity-time graph show?
The relationship between an object’s velocity and time.
Define free fall.
Motion of an object under the influence of gravity only.
True or false: Gravity affects all objects equally regardless of mass.
TRUE
All objects accelerate at approximately 9.81 m/s² near Earth’s surface.
What is the initial velocity in motion equations?
The velocity of an object at the start of the observation.
Fill in the blank: The kinematic equation relates displacement, initial velocity, time, and ______.
acceleration
What is terminal velocity?
The constant speed an object reaches when the force of gravity is balanced by drag.
Define scalar quantity.
A quantity that has only magnitude, such as speed or distance.
True or false: Position is a scalar quantity.
FALSE
Position is a vector quantity as it includes direction.
What is the unit of acceleration?
Meters per second squared (m/s²).
Fill in the blank: The total distance traveled is always ______ than or equal to displacement.
greater
What is uniform acceleration?
Acceleration that remains constant over time.
Define rest in motion.
A state where an object is not moving relative to a reference point.
True or false: Distance can be negative.
FALSE
Distance is always a positive value.
What does deceleration mean?
A decrease in the speed of an object.
Fill in the blank: An object in free fall accelerates at ______ m/s².
9.81
