Force and motion test

Front

What factors affect the force of friction between two surfaces?

Back

The force of friction depends on the smoothness of the surfaces in contact and the normal force acting between them.

Front

What type of force is applied when a person pushes a box across the floor?

Back

This is an applied force.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two masses, such as the Earth and an object, causing the object to fall towards the Earth.

Front

How do you calculate speed?

Back

Speed is calculated by dividing the distance traveled by the time taken (Speed = Distance / Time).

Front

What is net force?

Back

Net force is the total force acting on an object, taking into account all the individual forces acting on it.

Front

What is the relationship between mass and gravitational force?

Back

The gravitational force between two objects increases with greater mass and decreases with greater distance between them.

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on an object at rest, preventing it from moving, while kinetic friction acts on an object in motion.

Front

What is inertia?

Back

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

Front

How does surface area affect air resistance?

Back

Increased surface area generally increases air resistance, as there is more area for air molecules to collide with the object.

Front

What is the formula for calculating force?

Back

Force is calculated using the formula F = m * a, where F is force, m is mass, and a is acceleration.
