Forces

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It occurs when two surfaces come into contact with each other.

Front

What is gravity?

Back

Gravity is a force that attracts two objects with mass towards each other. It is what keeps us grounded on Earth.

Front

What is acceleration?

Back

Acceleration is how fast an object's speed changes over time. It can be caused by an increase or decrease in speed.

Front

What is tension?

Back

Tension is the force exerted by ropes, strings, or chains when they are pulled tight.

Front

What happens to acceleration when force increases?

Back

As force increases, acceleration increases.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a force.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity. It is a measure of how difficult it is to stop a moving object.

Front

What is a balanced force?

Back

Balanced forces are two or more forces acting on an object that cancel each other out, resulting in no change in motion.

Front

What is an unbalanced force?

Back

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

Front

What is the formula for calculating force?

Back

Force = mass x acceleration (F = m x a).
