What is the equation that relates distance traveled (s), initial velocity (u), acceleration (a), and time (t) for an object moving with uniform acceleration?

s = ut + ½ at^2

If an object moves in a circular path with uniform speed, what type of motion is being exhibited?

Uniform circular motion

What is the final velocity of a motorboat that starts from rest and accelerates at a constant rate of 3.0 m/s^2 for 8.0 seconds?

24 m/s

When driving to school, Abdul's average speed is 20 km/h. On his return trip, with less traffic, his average speed becomes 30 km/h. What is Abdul's average speed for the entire trip?

25 km/h

What is the displacement of an object that completes one round of a circular track of diameter 200 m?

When is a body said to be in uniform acceleration?

When it is accelerating at a constant rate

In the context of motion, what does negative acceleration signify?

Deceleration

What is the acceleration of a bus that decreases its speed from 80 km/h to 60 km/h in 5 seconds?

-8 km/h^2

How would you describe a body experiencing nonuniform acceleration?

Accelerating with varying rates

A train attains a speed of 40 km/h in 10 minutes with uniform acceleration. What is its acceleration?

-0.1 km/h^2

In the context of motion, what does a positive value for acceleration indicate?

Increase in velocity

1.2 m/s

In the scenario where a train is traveling at 90 km/h, and brakes produce a uniform acceleration of -0.5 m/s^2, how far will the train go before it is brought to rest?

550 m

If a trolley going down an inclined plane has an acceleration of 2 cm/s^2, what will be its velocity 3 seconds after the start?

10 cm/s
