Force, Mass, Acceleration (Flashcardizz)

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when two forces acting on an object are not equal, causing the object to accelerate in the direction of the greater force.

Front

What is net force?

Back

Net force is the overall force acting on an object after all the individual forces are combined. It determines the object's acceleration.

Front

How do you calculate force?

Back

Force can be calculated using the formula: Force (F) = Mass (m) × Acceleration (a).

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

If a 25kg bowling ball accelerates at 2m/s², what is the force applied?

Back

50N (calculated using F = m × a).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be caused by a change in speed or direction.

Front

What is the formula for acceleration?

Back

Acceleration (a) = Change in Velocity (Δv) / Time (t).

Front

If a 2kg bird is pushed by a force of 2N, what is its acceleration?

Back

1 m/s² (calculated using a = F/m).

Front

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

Back

The object remains at rest because the forces cancel each other out.
