Linear Motion review

Front

What does a velocity-time graph with a straight line indicate?

Back

Uniform acceleration.

Front

What is the formula to calculate acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

If an object accelerates at 15 m/s² and reaches a velocity of 50 m/s from rest, how long did it take to accelerate?

Back

3.3 seconds.

Front

What is the distance traveled by an object moving at a constant speed of 2 m/s for 20 seconds?

Back

40 meters.

Front

What is the definition of uniform motion?

Back

Motion at a constant speed in a straight line.

Front

How do you calculate the distance traveled under uniform acceleration?

Back

Distance = Initial Velocity × Time + 0.5 × Acceleration × Time².

Front

What is the distance covered by a dog that runs with an initial speed of 7.5 m/s and stops in 5 seconds?

Back

18.75 meters.

Front

What does a horizontal line on a velocity-time graph represent?

Back

No acceleration (constant velocity).

Front

If an object travels 10 meters in 20 seconds, what is its speed?

Back

0.5 m/s.

Front

What is the significance of the area under a velocity-time graph?

Back

It represents the distance traveled.
