1D Motion Test Review

Front

What is 1D motion?

Back

1D motion refers to the movement of an object along a straight line, characterized by its position, velocity, and acceleration.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time, measured in meters per second squared (m/s²).

Front

How do you calculate distance traveled under uniform acceleration?

Back

Distance (d) can be calculated using the formula: d = ut + (1/2)at², where u is the initial velocity, a is acceleration, and t is time.

Front

What is the significance of an object's mass in free fall?

Back

In free fall, the mass of an object does not affect the time it takes to fall; all objects fall at the same rate in a vacuum.

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, including direction.

Front

What does it mean for an object to have zero displacement?

Back

An object can have zero displacement if it returns to its starting point, regardless of the distance traveled.

Front

What is uniform motion?

Back

Uniform motion occurs when an object moves at a constant speed in a straight line.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity representing how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is the effect of air resistance on falling objects?

Back

Air resistance opposes the motion of falling objects, affecting their acceleration and terminal velocity.

Front

What is terminal velocity?

Back

Terminal velocity is the constant speed an object reaches when the force of gravity is balanced by air resistance.
