What is a rectilinear motion?

• displacement (s), velocity (v), and acceleration (a) of a particle as it moves along a curved line in 2D
• displacement (s), velocity (v), and acceleration (a) of a particle as it moves along a wavy line
• displacement (s), velocity (v), and acceleration (a) of a particle as it moves along a straight line
• displacement (s), velocity (v), and acceleration (a) of a particle as it moves along a curved line in 3D

What is velocity (v)?

• The distance traveled per unit time
• The rate of change of displacement with respect to time
• The total distance covered
• The speed of an object without direction

A car accelerates from rest at 2 m/s². What is its velocity after 5 seconds?

• 10 m/s
• 5 m/s
• 2.5 m/s
• 20 m/s

Which of the following is the correct unit for acceleration?

• m/s
• m/s²
• km/h
• N

Speed has both magnitude and direction

A ball is thrown upward with an initial velocity of 15 m/s. What is its velocity at the highest point?

• -9.81 m/s
• 0 m/s
• -9.81 m/s
• 15 m/s

Which equation is used when acceleration is constant and time is unknown?

• s = ut + 1/2at²
• v = u + at
• v² = u² + 2as
• s = vt

If an object covers equal distances in equal intervals of time, it is said to have:

• Accelerated motion
• Circular motion
• Non-uniform motion
• Uniform motion

Velocity is the rate of change of displacement.

What is the shortest distance between two points called?

• Displacement

• displacement

• Displacement.

• displacement.

• DISPLACEMENT

Which of the following is an example of rectilinear motion?

• A ceiling fan rotating
• A child swinging on a swing
• A train moving on a straight track
• Earth revolving around the sun

A bus starts from rest and speeds up in a straight line. This is an example of:

• Uniform motion
• Accelerated rectilinear motion
• Oscillatory motion
• Circular motion

A stone falls freely under gravity. Which force causes this rectilinear motion?

• Friction
• Magnetic
• Gravitational
• Electric

Acceleration is zero in uniform motion

Which of the following is an example of non-uniform rectilinear motion?

• A ball dropped freely under gravity
• A car moving at constant speed on a straight road
• A train moving on a straight track at constant speed
• A cyclist moving at constant velocity
