Forces Week 2: Types of Forces

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, caused by the contact between two surfaces.

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

What is a push in terms of forces?

Back

A push is a force that moves an object away from the source of the force.

What are unbalanced forces?

Back

Unbalanced forces are forces that do not cancel each other out, resulting in a change in the motion of an object.

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size and opposite in direction, resulting in no change in motion.

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.

What is the difference between contact and non-contact forces?

Back

Contact forces require physical contact between objects (e.g., friction, tension), while non-contact forces act at a distance (e.g., gravity, magnetic force).

Front

What is tension?

Back

Tension is a pulling force transmitted through a string, rope, or cable when it is pulled tight by forces acting from opposite ends.

What is the role of mass in gravitational force?

Back

The gravitational force between two objects increases with the mass of the objects and decreases with the square of the distance between them.

What is the effect of friction on motion?

Back

Friction can slow down or stop the motion of an object, depending on the surfaces in contact and the amount of force applied.
