Unit 2 Midterm Review

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be positive (speeding up), negative (slowing down), or zero (constant velocity).

Front

What does positive acceleration indicate?

Back

Positive acceleration indicates that an object is increasing its velocity over time.

Front

What does negative acceleration indicate?

Back

Negative acceleration, also known as deceleration, indicates that an object is decreasing its velocity over time.

Front

What is constant velocity?

Back

Constant velocity means an object is moving at a fixed speed in a straight line without changing direction.

Front

How can an object accelerate without changing speed?

Back

An object can accelerate by changing direction while maintaining a constant speed, such as a car turning around a curve.

Front

What is the relationship between acceleration and velocity?

Back

Acceleration is the change in velocity over time. If velocity increases, acceleration is positive; if velocity decreases, acceleration is negative.

Front

What is an example of an object accelerating?

Back

A car speeding up from a stoplight or a roller coaster going down a hill are examples of acceleration.

Front

What does it mean for an object to move at a constant speed?

Back

Moving at a constant speed means the object covers equal distances in equal intervals of time without speeding up or slowing down.

Front

What is the formula for acceleration?

Back

The formula for acceleration (a) is a = (final velocity - initial velocity) / time.

Front

What is circular motion?

Back

Circular motion is the motion of an object traveling along a circular path, which involves constant acceleration due to changing direction.
