Front

What is Newton's 3rd Law of Motion?

Back

When one object exerts a force on a second object, the second object exerts a force on the first that is equal in strength but opposite in direction.

Front

What is acceleration?

Back

The change in velocity divided by the time it took for the change to occur; or how fast the velocity changes.

Front

What does it mean for an object to be in motion?

Back

A change in position must occur for an object to be considered in motion.

Front

What is negative acceleration?

Back

It refers to a decrease in speed, often represented in a graph where the slope is downward.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

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 momentum?

Back

Momentum is the product of an object's mass and its velocity, represented as p = mv.

Front

What is the significance of a force diagram?

Back

A force diagram visually represents all the forces acting on an object, helping to analyze motion and predict outcomes.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion; it is directly related to mass.

Front

What is the relationship between mass and acceleration in Newton's 2nd Law?

Back

According to Newton's 2nd Law, Force = Mass x Acceleration; this means that for a given force, an increase in mass results in a decrease in acceleration.
