speed, velocity, acceleration

Front

What does Newton's First Law state?

Back

An object at rest will remain at rest unless a force is applied.

Front

What is the definition of velocity?

Back

The speed of an object in a particular 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 acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is an example of acceleration?

Back

A car increasing its speed from 30 mph to 60 mph.

Front

What type of force causes a change in an object's motion?

Back

An unbalanced force.

Front

What is the formula for calculating acceleration?

Back

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

Front

What is the unit of measurement for acceleration?

Back

Meters per second squared (m/s²).

Front

How does gravity affect acceleration?

Back

Gravity causes objects to accelerate towards the Earth at approximately 9.81 m/s².

Front

What is the relationship between velocity and time?

Back

Velocity can change over time, and this change is described as acceleration.
