ES Topic 4 Test

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

What is constant speed?

Back

Constant speed refers to a speed that does not change over time. An object moving at constant speed covers equal distances in equal intervals of time.

Front

What does Newton's 3rd Law state?

Back

Newton's 3rd Law states that for every action, there is an equal and opposite reaction. This explains how a balloon moves in the opposite direction when air is released.

Front

What is a reference point?

Back

A reference point is a place or object used to determine whether something is in motion. It provides a basis for comparison.

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken. Formula: Average Speed = Total Distance / Total Time.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction. It is a vector quantity, meaning it has both magnitude and direction.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is Newton's 1st Law of Motion?

Back

Newton's 1st Law states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by a net external force.

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Formula: F = ma.

Front

What is a force?

Back

A force is a push or pull acting upon an object. It can cause an object to accelerate, decelerate, or change direction.
