Motion and Acceleration Quiz

What are the equations of motion with constant acceleration?

• v = u + at, s = ut + 0.5at^2, v^2 = u^2 + 2as

• v = u + at, s = ut + 0.5at^2, v^2 = u^2 + 2as + at

• v = u + at, s = ut + 0.5at^2, v^2 = u^2 + 2as + t

• v = u + at, s = ut + 0.5at^2, v^2 = u^2 + as

How can motion with constant acceleration be represented graphically?

• Curved line with varying slope

• Straight line with varying slope

• Straight line with no slope

• Straight line with constant slope

What is the formula for calculating displacement with constant acceleration?

• displacement = initial velocity * time + acceleration

• displacement = initial velocity * time - (1/2) * acceleration * time^2

• displacement = initial velocity * time + (1/2) * acceleration * time

• displacement = initial velocity * time + (1/2) * acceleration * time^2

Give an example of an application of constant acceleration in real life.

• person running a marathon

• car accelerating from a stop sign

• rocket launching into space

• object falling freely due to gravity

What is the initial velocity in the equation of motion with constant acceleration?

• The initial velocity is the velocity at the end of the motion.

• The initial velocity is the average velocity during the motion.

• The initial velocity is the maximum velocity during the motion.

• The initial velocity is the velocity at the start of the motion.

How is acceleration related to velocity in motion with constant acceleration?

• Acceleration is inversely related to velocity in motion with constant acceleration.

• Acceleration has no relation to velocity in motion with constant acceleration.

• Acceleration is equal to velocity in motion with constant acceleration.

• Acceleration is directly related to velocity in motion with constant acceleration.

What is the formula for calculating final velocity in motion with constant acceleration?

• v = u + at

• v = u * at

• v = u - at

• v = u + at^2

Explain the concept of positive acceleration in motion with constant acceleration.

• Positive acceleration refers to a change in direction of motion at a constant rate.

• Positive acceleration refers to an increase in velocity over time at a constant rate.

• Positive acceleration refers to a decrease in velocity over time at an increasing rate.

• Positive acceleration refers to a decrease in velocity over time at a constant rate.

What is the formula for calculating time in motion with constant acceleration?

• t = (v + u) / a

• t = (v * u) / a

• t = (v - u) / a

• t = (v - u) * a

How can you determine the direction of acceleration in motion with constant acceleration?

• Consider the direction of the time

• Consider the direction of the displacement

• Consider the direction of the velocity only

• Consider the direction of the force and velocity
