Eng Physics 5.1 Formative

Front

What is a force?

Back

A force is a push or a pull.

Front

Why are forces considered vectors?

Back

Forces are considered vectors because they have both magnitude and direction.

Front

What happens to the acceleration of an object if the net force acting on it triples in magnitude?

Back

The acceleration triples.

Front

How do you calculate net force?

Back

Net force can be calculated using the formula: Net Force = mass × acceleration.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is the formula for calculating acceleration?

Back

Acceleration = Net Force / Mass.

Front

If a car has a mass of 1400 kg and accelerates at 1.85 m/s², what is the net force acting on it?

Back

The net force is 2590 N.

Front

What is the acceleration of an object if the net force is 4.3 x 10^5 N and its mass is 3.5 x 10^5 kg?

Back

The acceleration is -1.23 m/s².

Front

What does it mean when an object is in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero.

Front

What is the relationship between mass and acceleration in Newton's second law?

Back

According to Newton's second law, acceleration is directly proportional to net force and inversely proportional to mass.
