What happens when two forces are unbalanced?

Back

The object will move in the direction of the greater force.

Front

What is the independent variable in an experiment?

Back

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

At both poles of the magnet.

Front

How can you increase the speed of an object you are pushing?

Back

The mass of the object and the acceleration due to gravity.

Front

What is the effect of adding salt to ice?

Back

It lowers the freezing point of the ice, causing it to melt faster.

Front

What is the relationship between mass and gravitational force?

Back

The greater the mass of an object, the greater the gravitational force it exerts.

Front

What is a balanced force?

Back

When two forces acting on an object are equal in size but opposite in direction, resulting in no movement.

Front

What is the role of the control in an experiment?

Back

The control is a standard for comparison that is not changed during the experiment.
