Net Force Review

Front

What is net force?

Back

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

Front

What is the formula for calculating force?

Back

F = MA, where F is force, M is mass, and A is acceleration.

Front

How do you calculate mass using force and acceleration?

Back

M = F/A, where M is mass, F is force, and A is acceleration.

Front

What happens to an object's acceleration if the net force acting on it is zero?

Back

If the net force is zero, the object will not accelerate; it will either remain at rest or continue moving at a constant velocity.

Front

What is acceleration?

Back

Acceleration is the rate at which an object's velocity changes over time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

When two forces act in the same direction, how do you find the net force?

Back

You add the magnitudes of the two forces together to find the net force.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

If a 50 kg box is pushed with a force of 100 N, what is its acceleration?

Back

2 meters per second squared (A = F/M = 100 N / 50 kg).

Front

If a box is accelerating at 3 m/s² with a net force of 150 N, what is its mass?

Back

50 kg (M = F/A = 150 N / 3 m/s²).
