What is an Elastic Collision?

Back

An elastic collision is a type of collision where both momentum and kinetic energy are conserved. In this type of collision, the objects bounce off each other without any loss of energy.

Front

What is an Inelastic Collision?

Back

An inelastic collision is a type of collision where momentum is conserved, but kinetic energy is not. In this type of collision, the objects may stick together or deform, resulting in a loss of kinetic energy.

Front

What does it mean when a bus is Accelerating?

Back

When a bus is accelerating, it means that its speed is increasing over time. For example, if a bus's speed changes from 0 to 10 m/s in 5 seconds, it is accelerating.

Front

What does it mean when a bus is Decelerating?

Back

Decelerating means that the bus is slowing down. Its speed is decreasing over time.

Front

What does Constant Speed mean?

Back

Constant speed means that an object is moving at the same speed over time, without speeding up or slowing down.

Front

What is represented on the y-axis of a graph?

Back

The y-axis of a graph typically represents the dependent variable, which is the variable being measured or observed. For example, in a graph showing bacteria growth, the y-axis would represent the number of bacteria.

Front

What does a graph showing Acceleration look like?

Back

A graph showing acceleration typically has a curve that indicates a change in speed over time, rather than a straight line, which would indicate constant speed.

Front

What does it mean if runners are moving at the same speed on a graph?

Back

If runners are moving at the same speed on a graph, their lines will be parallel and equidistant from each other, indicating that they are covering the same distance in the same amount of 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 a Dependent Variable?

Back

A dependent variable is the variable that is being measured in an experiment or graph. It depends on the independent variable.
