PMA Practice - Qtr 1 & 2

Front

What is steady speed?

Back

Steady speed is when an object moves at a constant rate without speeding up or slowing down.

Front

What is the independent variable in an experiment?

Back

The independent variable is the factor that is changed or controlled in an experiment to test its effects on the dependent variable.

Front

What is the dependent variable in an experiment?

Back

The dependent variable is the factor that is measured or observed in an experiment, which is affected by the independent variable.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state, such as an object at a height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, which depends on its mass and speed.

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined.

Front

What does it mean for an object to be stationary?

Back

An object is stationary when it is not moving and remains in the same position.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity, which can involve speeding up, slowing down, or changing direction.

Front

What is the role of control variables in an experiment?

Back

Control variables are the factors that are kept constant to ensure that the results of the experiment are due to the independent variable.

Front

What is the significance of direction in force?

Back

The direction of a force is important because it determines how the force will affect the motion of an object.
