8.PS2.3 Kinematics

Front

What is Kinematics?

Back

Kinematics is the branch of physics that describes the motion of objects without considering the forces that cause the motion.

Front

What is acceleration?

Back

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

Front

What does a distance vs. time graph represent?

Back

A distance vs. time graph shows how far an object has traveled over a specific period of time.

Front

What does a speed vs. time graph represent?

Back

A speed vs. time graph shows how the speed of an object changes 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 a free-falling object?

Back

A free-falling object is one that is falling under the influence of gravity only, with no other forces acting on it.

Front

What is the role of unbalanced forces in motion?

Back

Unbalanced forces cause an object to accelerate, change direction, or change speed.

Front

What happens to an object's motion when forces are balanced?

Back

When forces are balanced, an object remains at rest or continues to move at a constant speed in a straight line.

Front

What is negative acceleration?

Back

Negative acceleration, also known as deceleration, occurs when an object slows down.

Front

What is the significance of a horizontal line on a distance vs. time graph?

Back

A horizontal line indicates that the object is stationary and not changing its position over time.
