Force and Motion

Front

What is force?

Back

A force is a push or pull acting on an object, measured in Newtons (N).

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is net force?

Back

Net force is the total force acting on an object after all the individual forces are combined.

Front

What are the two types of forces?

Back

Contact forces (forces that require contact) and non-contact forces (forces that act at a distance, like gravity).

Front

What is inertia?

Back

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

Front

What is the relationship between mass and force?

Back

The greater the mass of an object, the greater the force needed to change its motion.

Front

What happens when forces are balanced?

Back

When forces are balanced, the net force is zero, and the object remains at rest or continues to move at a constant speed.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the net force is not zero, causing the object to accelerate in the direction of the greater force.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, measured in meters per second squared (m/s²).

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).
