Forces and Net Force

Front

What force holds the planets in motion around the sun?

Back

Gravitational force is the force that attracts two bodies towards each other, keeping planets in orbit around the sun.

What happens when two teams pull with the same amount of force?

Back

If two teams pull with the same amount of force, they will not move at all, resulting in a balanced force.

What is the net force?

Back

Net force is the overall force acting on an object after all the forces are combined. For example, if a force of 3 N is applied to the right, the net force is 3 N, right.

What causes an object to move?

Back

Unbalanced forces cause an object to move. When forces acting on an object are not equal, the object will accelerate in the direction of the greater force.

Who wins the tug of war with what net force?

Back

The person on the left with 20 N wins the tug of war if the opposing force is less than 20 N.

Front

What is a balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when one force is greater than the other, causing a change in motion.

Front

What is the formula for calculating net force?

Back

Net force = Total forces acting in one direction - Total forces acting in the opposite direction.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting in the opposite direction of the movement.
