Phy. Sci.- Motion, speed, acceleration, forces (ch.2 review)

Front

What is acceleration?

Back

The rate at which velocity changes over time, which can involve changes in speed, direction, or both.

Front

What does constant speed mean?

Back

When an object covers equal distances in equal intervals of time without changing its speed.

Front

Provide an example of an accelerating object.

Back

A toy train traveling in a circle, as it changes direction.

Front

How do you calculate distance traveled?

Back

Distance = Speed × Time.

Front

What is deceleration?

Back

A decrease in speed or a negative acceleration.

Front

What is the formula for calculating speed?

Back

Speed = Distance / 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 happens to an object in motion when no net forces act on it?

Back

It continues to move at a constant speed in a straight line.

Front

What is the unit of acceleration?

Back

Meters per second squared (m/s²).

Front

What does a negative acceleration indicate?

Back

It indicates that an object is slowing down or decelerating.
