1D Ratio Qs

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time. It can be calculated as the change in velocity divided by the time taken.

Front

If two objects start from rest and one accelerates twice as much as the other, how much faster will it be after the same time?

Back

It will be twice as fast.

Front

What is the relationship between distance traveled and time when acceleration is constant?

Back

The distance traveled is proportional to the square of the time when starting from rest, given by the formula: distance = 0.5 * acceleration * time^2.

Front

If an object travels twice the distance of another object under the same acceleration, how does their final velocity compare?

Back

The object that traveled twice the distance will have four times the final velocity.

Front

What is the formula for calculating final velocity when starting from rest?

Back

Final velocity (v) = acceleration (a) * time (t).

Front

If two objects have the same acceleration but one travels twice as long, how much farther does it go?

Back

It goes four times farther.

Front

What does it mean if an object has half the acceleration of another object?

Back

It means that for the same amount of time, the object with half the acceleration will have a final velocity that is half of the other object's final velocity.

Front

How does acceleration affect the speed of an object over time?

Back

Acceleration increases the speed of an object over time; the greater the acceleration, the faster the increase in speed.

Front

What is the relationship between acceleration and velocity?

Back

Acceleration is the change in velocity over time; if acceleration is positive, velocity increases, and if negative, velocity decreases.

Front

If two objects are identical and one is accelerated to twice the speed of the other, how does their acceleration compare?

Back

The acceleration of the faster object is twice that of the slower object, assuming they were accelerated for the same time.
