AP Phys. 1 Unit 1 Review

Front

What is average velocity?

Back

Average velocity is the total displacement divided by the total time taken. It is a vector quantity, meaning it has both magnitude and direction.

Front

How do you calculate acceleration?

Back

Acceleration is calculated by the formula: a = (final velocity - initial velocity) / time.

Front

What is the formula for calculating distance when acceleration is constant?

Back

The formula is: d = v_i * t + 0.5 * a * t^2, where d is distance, v_i is initial velocity, a is acceleration, and t is time.

Front

What does it mean for an object to be in motion?

Back

An object is in motion if its position changes relative to a reference point over time.

Front

What is the difference between speed and velocity?

Back

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

Front

What is the significance of a negative acceleration?

Back

Negative acceleration, or deceleration, indicates that an object is slowing down.

Front

How do you determine the direction of velocity?

Back

The direction of velocity is determined by the direction of the object's displacement over time.

Front

What is a free body diagram?

Back

A free body diagram is a graphical representation used to visualize the forces acting on an object.

Front

What is the role of friction in motion?

Back

Friction is a force that opposes the motion of an object, affecting its acceleration and velocity.

Front

How can you tell if an object is accelerating?

Back

An object is accelerating if its velocity is changing over time, which can be indicated by a change in speed or direction.
