Physics Sem 1 Review 2

Front

What happens to an object tossed straight up in a moving train?

Back

The object will land back in the thrower's arms due to inertia, as it retains the forward motion of the train.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = Net Force (F) / Mass (m)

Front

If the net force on an object is quadrupled, what happens to its acceleration?

Back

The acceleration also quadruples, according to Newton's second law (F = ma).

Front

How do you calculate the mass of an object if you know the net force and acceleration?

Back

Mass (m) = Net Force (F) / Acceleration (a)

Front

What is the acceleration of a system of two blocks on a frictionless surface when a force is applied?

Back

The acceleration can be calculated using the total mass of the system and the applied force.

Front

What does a constant acceleration of 6 m/s² imply about an object's velocity?

Back

The object's velocity increases by 6 m/s every second.

Front

What is inertia?

Back

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

Front

Define net force.

Back

Net force is the vector sum of all the forces acting on an object.

Front

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

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is the formula for calculating net force?

Back

Net Force (F) = Mass (m) x Acceleration (a)
