Week 15 Warm Up

Front

What is inertia?

Back

Inertia is the property of an object to remain at rest or in uniform motion unless acted upon by an external force.

Front

What is the definition of velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What does a horizontal line on a distance-time graph indicate?

Back

A horizontal line indicates that the object is at rest, as there is no change in distance over time.

Front

How do you calculate speed?

Back

Speed is calculated by dividing the distance traveled by the time taken (Speed = Distance / Time).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can occur when an object speeds up, slows down, or changes direction.

Front

What is the formula for acceleration?

Back

Acceleration can be calculated using the formula: 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 factors affect the speed of an object?

Back

Factors that affect speed include the object's mass, the force applied to it, and the friction acting against it.

Front

What is a distance-time graph?

Back

A distance-time graph is a graphical representation that shows how distance changes over time, helping to visualize an object's motion.

Front

What does it mean when an object has constant speed?

Back

Constant speed means that the object covers equal distances in equal intervals of time, regardless of the duration.
