Intro to Motion Review

Front

What is the condition for a car to have no acceleration?

Back

A car travelling on a straight road with constant speed has no acceleration.

Front

What happens to an object's motion when it speeds up, slows down, or changes direction?

Back

The object's motion is described as acceleration.

Front

How is speed defined in terms of distance and time?

Back

Speed is the distance an object moves divided by the time it took to move that distance.

Front

What is the initial velocity of an object that is dropped from rest?

Back

The initial velocity of the object is 0 m/s.

Front

What is the difference between distance and displacement?

Back

Displacement is the distance between the initial position and the final position.

Front

What is the formula for calculating acceleration?

Back

Acceleration is calculated as the change in velocity divided by the time taken.

Front

What is the unit of measurement for speed in the metric system?

Back

The unit of measurement for speed in the metric system is meters per second (m/s).

Front

What does a negative acceleration indicate about an object's motion?

Back

Negative acceleration indicates that the object is slowing down.

Front

What is the relationship between velocity and displacement?

Back

Velocity is the rate of change of displacement with respect to time.

Front

What is the significance of a constant speed in motion?

Back

Constant speed means that the object is moving the same distance in equal intervals of time, indicating no acceleration.
