What is force?

Back

Force is a push or pull that can change the motion of an object.

Front

What are the two types of forces?

Back

The two types of forces are contact forces and non-contact forces.

Front

What does it mean if forces are balanced?

Back

Balanced forces mean that the total force acting on an object is zero, resulting in no change in motion.

Front

What does it mean if forces are unbalanced?

Back

Unbalanced forces result in a change in motion, causing the object to accelerate in the direction of the greater force.

Front

What is the unit of force?

Back

The unit of force is Newton (N).

Front

How do you calculate force?

Back

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

Front

What is mass?

Back

Mass is the amount of matter in an object, usually measured in kilograms (kg).

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity, measured in meters per second squared (m/s²).

Front

If a 10 kg object is accelerating at 2 m/s², what is the force?

Back

Force = 10 kg x 2 m/s² = 20 N.

Front

What direction will an object move if a force is applied to the left?

Back

The object will move to the left.
