Forces and Motion

Front

What is net force?

Back

The net force is the total force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

What does it mean for forces to be balanced?

Back

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

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces are not equal and opposite, causing a change in the object's motion.

Front

How do you calculate net force?

Back

Net force is calculated by adding all the forces acting on an object, taking into account their direction.

Front

What happens to an object at rest when balanced forces act on it?

Back

An object at rest will remain at rest when balanced forces act on it.

Front

What happens to an object in motion when balanced forces act on it?

Back

An object in motion will continue to move at a constant velocity when balanced forces act on it.

Front

What is friction?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can occur due to unbalanced forces.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = mass (m) x acceleration (a).
