Ch. 3 Accelerated Motion

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time. It is a vector quantity, meaning it has both magnitude and direction.

What is the formula for acceleration?

Front

What is the difference between velocity and speed?

Back

Velocity is a vector quantity that refers to the rate at which an object changes its position, including direction. Speed is a scalar quantity that refers only to how fast an object is moving, regardless of direction.

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, along with the direction. It is a vector quantity.

Front

What is the formula for displacement in uniformly accelerated motion?

Back

Front

What does it mean if an object has negative velocity?

Back

Negative velocity indicates that the object is moving in the opposite direction of the defined positive direction.

Front

What is the relationship between acceleration and velocity?

Back

Acceleration indicates how the velocity of an object changes over time. If acceleration and velocity are in the same direction, the object speeds up; if they are in opposite directions, the object slows down.

Front

What is the formula for final velocity in terms of initial velocity, acceleration, and displacement?

Back

Front

What is uniform acceleration?

Back

Uniform acceleration occurs when an object's velocity changes at a constant rate over time.

Front

What is the significance of the area under a velocity-time graph?

Back

The area under a velocity-time graph represents the displacement of the object over that time interval.
