# Kinematics Quiz 1

#### Quiz Description

In this quiz, we shall study one important aspect of physics known as kinematics. We shall look at velocity, speed, and velocity - time graphs, acceleration, etc. Graphs are something very common you would find in this topic, implying that knowing it to your fingertips is a plus for you. Answering the quiz will give you an upper hand in the understanding of kinematics as a whole.

Kinematics is a branch of mechanics that studies the motion of a point, body, or group of objects, without considering the cause of the motion. This topic greatly focuses on aspects like acceleration and velocity. To describe the motion of celestial bodies, astrophysicists make use of kinematics. Kinematics could also be applied in biomechanics by describing the motion of the skeletal system.

Now we have come to realize how important this quiz is to anyone studying kinematics. Are you looking for a way of understanding this topic? All you need to do is take the A level physics quiz, and challenge yourself. Good luck!

A car begins to move. It speeds up until it reaches a constant speed. It continues to travel at this constant speed for the rest of the journey.

What happens to the acceleration and what happens to the velocity of the car during the journey?

Correct
• Both the acceleration and the velocity change.
• Only the acceleration changes.
• Only the velocity changes.
• Neither the acceleration nor the velocity changes.

• C
• D

The graph shows how the speed of a car travelling in a straight line changes with time.

Which section shows the largest acceleration? Correct
• A
• B
• C
• D

An object falls from rest through the air and the air resistance on it increases. The object reaches terminal velocity.

Which quantity decreases until its terminal velocity is reached?

Correct
• acceleration
• kinetic energy
• speed
• weight

An object falls from rest through the air. Its velocity increases until it reaches terminal velocity.

Which quantity increases until its terminal velocity is reached?

Correct
• acceleration
• air resistance

The speed-time graph represents a short journey. Correct
• A
• B
• C
• D

When a heavy coin falls a short distance towards the ground it does not reach terminal velocity.

Why is this?

Correct
• The coin has not hit the ground.
• The weight of the coin equals the air resistance.
• The weight of the coin increases as air resistance increases.
• The weight of the coin is always more than air resistance.
