What are balanced forces?

Back

Balanced forces are forces acting on an object that are equal in size and opposite in direction, resulting in no change in the object's motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal and opposite, causing a change in the object's motion, such as starting to move, stopping, or changing direction.

What happens to an object in motion when the net force acting on it is zero?

Back

An object in motion will continue to move in a straight line at a constant speed if the net force acting on it is zero.

Front

What is the relationship between force and motion?

Back

For an object to move at a constant speed, the forces acting on it must be balanced. If the object is accelerating, the forces must be unbalanced.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

If a box is pushed with a force of 5 N to the left and has a friction force of 5 N to the right, what will happen?

Back

The box will not move because the forces are balanced (5 N left and 5 N right).

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 the formula for calculating force?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, measured in kilograms (kg), while weight is the force of gravity acting on that mass, measured in Newtons (N).
