Motion Test Review

Front

What is a scalar?

Back

A scalar is a quantity that has only magnitude and no direction.

Front

What is a vector?

Back

A vector is a quantity that has both magnitude and direction.

Front

How do you calculate acceleration?

Back

Acceleration is calculated by the formula: (final velocity - initial velocity) / time.

Front

What is the formula for calculating distance?

Back

Distance = speed × time.

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position, considering direction.

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the straight line distance from start to end.

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

If a car speeds up from 10 m/s to 30 m/s in 5 seconds, what is its acceleration?

Back

Acceleration = (30 m/s - 10 m/s) / 5 s = 4 m/s².

Front

What does it mean if an object is in motion?

Back

An object is in motion if its position changes relative to a reference point.

Front

What is the rate of change of velocity?

Back

The rate of change of velocity is known as acceleration.
