Unit 2 Investigating Forces & Motion

Front

applied force

Back

Applied force is a force that is applied on an object by a person or another object.

Front

balanced forces

Back

Balanced forces are equal and opposite forces on an object that result in no change in position, direction, or motion; combined net force equals zero.

Front

friction

Back

Friction is a force that acts in the opposite direction to movement.

Front

gravity

Back

Gravity is a force that pulls objects toward each other.

Front

magnetism

Back

Magnetism is a force that pushes or pulls a magnetic material across a distance.

Front

net force

Back

Net force is the measurement of the total forces exerted on an object, measured in Newtons (N).

Front

Newton’s Third Law of Motion

Back

For every force applied to an object, there is a simultaneous force applied that is equal in magnitude and opposite in direction.

Front

normal force

Back

Normal force is a force exerted on an object that is in contact with another object.

Front

simultaneous force pairs

Back

Simultaneous force pairs are forces that occur in opposite directions and equal strengths at the point of contact between objects.

Front

unbalanced forces

Back

Unbalanced forces are unequal forces on an object that may result in a change in motion; calculated net force is not equal to zero.
