What is constant velocity?

Back

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

Front

What does a velocity-time graph represent?

Back

A velocity-time graph shows how the velocity of an object changes over time.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity. It can be positive (speeding up) or negative (slowing down).

Front

What does it mean if an object is not moving?

Back

If an object is not moving, its velocity is zero.

Front

What is positive acceleration?

Back

Positive acceleration occurs when an object's speed increases over time.

Front

What is negative acceleration?

Back

Negative acceleration, also known as deceleration, occurs when an object's speed decreases over time.

Front

What happens to an object's velocity when it makes a turn?

Back

When an object makes a turn, it experiences acceleration because 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 does it mean for an object to have a constant speed?

Back

An object has a constant speed if it covers equal distances in equal intervals of time, regardless of its direction.

Front

What is a straight-line motion?

Back

Straight-line motion refers to the movement of an object along a straight path.
