Unit 2 Midterm Review

Front

What is positive acceleration?

Back

Positive acceleration occurs when an object increases its velocity over time.

Front

What is negative acceleration?

Back

Negative acceleration, also known as deceleration, occurs when an object decreases its velocity over time.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What is displacement?

Back

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

Front

How does changing direction affect acceleration?

Back

An object can be accelerating even if its speed is constant if its direction is changing.

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 happens to acceleration when an object moves in a circular path at constant speed?

Back

The object experiences acceleration due to the continuous change in direction, even though its speed remains constant.

Front

If a runner completes a lap around a track and returns to the starting point, what is their displacement?

Back

The displacement is 0 m, as they have not changed their position.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) can be calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What is uniform acceleration?

Back

Uniform acceleration occurs when an object's acceleration is constant over time.
